a car is initially moving at 10 m/s and accelerates at a constant rate of 2 m/s^2 for 4 seconds, in a straight line. How far did the car carvel during this time?
Answers
A car is initially moving at 10 m/s and accelerates at a constant rate of 2 m/s², then the car will travel 56 meters.
What is Acceleration?The rate of change in an object's velocity concerning time is known as acceleration in mechanics. The vector quantity of accelerations. The direction of the net force that is acting on an object determines its acceleration.
Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is a vector quantity as well. The definition of acceleration is the change in velocity vector over a time interval divided by the time interval.
There are several types of acceleration :
Uniform AccelerationNon-Uniform AccelerationAverage AccelerationAccording to the question, the given values are :
Initial Speed, u = 10 m/s
Acceleration, a = 2 m/s²

What is inertia?
Inertia is the resistance of an object to any change in motion. Inertia is proportional the mass of the object: in fact, as we experience in common situations, the larger the mass of an object, the more difficult it is to change its motion.
Inertia of an object is its inherited property. It is the measure of its mass. It is clear that the inertia of an object depends directly on its mass. Mass of an object is the amount of matter contained in it. It is same at every location.

What is the displacement of the ride between 0s and 16 s?
Answers
Answer:
See attached answer.
Explanation:
To solve this we must be knowing each and every concept related to displacement and its calculations. Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.
What is displacement?The distance along a straight line connecting an object's original and final positions is its displacement [x].
Displacements are not always a good thing. It may also be 0 or negative. A negative displacement indicates that the item has moved away from the origin and toward the right if a positive direction is situated to the right of both the origin.
If the body's velocity at a given moment in time is 'v' m/s, then displacement may be expressed mathematically as-
v = dx /dt
dx = vdt
Integrating on both sides, we get
∫dx = ∫vdt
∫dx [x = 0 to x = x] = ∫vdt [ t = 0 to t = 16 s]
x = v [16 - 0]
x = 16v
Therefore, the ride's displacement from time t = 0 s to time t = 16 s is 16v.

turns on the engines that transforms the chemical energy of its components into mechanical energy that they supply to the rocket, so that the amount of chemical energy of the fuel decreases and increases the potential energy (height) and the kinetic energy (speed).
Explanation:
In this exercise we must describe what happens when a rocket is launched.
At the beginning, the whole system is at rest, the force is the weight and the normal.
At this time, it turns on the engines that transforms the chemical energy of its components into mechanical energy that they supply to the rocket, so that the amount of chemical energy of the fuel decreases and increases the potential energy (height) and the kinetic energy (speed). At this point, the system can also be analyzed by an increase in its momentum due to the impulse given by the engines, the two forms of analysis are correct and allow to find different magnitudes of the system, we must emphasize that the mass of the rocket decreases, but the rocket mass plus exhaust gases remains constant.
At that point when the rocket begins to climb, the support on the Earth decreases to zero and the Normal Force is zero.
When all the chemical energy of the engines is finished, they are released and other engines are turned on that, as the weight has decreased, can continue to give energy to the rocket to continue its increase in scientific and potential energy. In this second case, the impulse is different since other fuels are used, it is appropriate to clarify that the weight of the rocket decreases due to the loss of mass of the engines that were released and also due to the decrease in the force of gravity of the planet with height
In the attachment we can see a diagram of the moment of clearance, just after the normal force becomes zero

A ball at rest rolls across a frictionless floor at 12.0 m/s/s. How far will it travel in
8.00 s?
Answers
Answer:
The distance, d travelled by the ball is 768 metres.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of final speed from the initial speed all over time.
Hence, if we subtract the final speed from the initial speed and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{initial \; speed - final \; speed}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is initial and final speed respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Given the following data;
Acceleration = 12.0m/s²
Time, t = 8secs
Velocity =?
First, we would calculate its velocity;
[tex]a = \frac{v - u}{t}[/tex]
Since the ball rolls at rest, initial velocity is zero (0).
[tex]V = a * t[/tex]
[tex]V = 12 * 8[/tex]
[tex]Velocity = 96ms^{-1}[/tex]
We can now solve for the distance;
[tex] Velocity = \frac{distance}{time}[/tex]
Therefore,
[tex]Distance = velocity * time[/tex]
[tex]Distance = 96 * 8[/tex]
Distance = 768m.

C (Celsius) is the correct symbol for the metric (SI) unit of temperature. The correct option is D.
The Celsius scale is widely used for measuring temperature in the metric system.
The symbol "°C" is used to represent degrees Celsius. It is named after the Swedish astronomer Anders Celsius, who introduced the scale in the 18th century.On the Celsius scale, the freezing point of water is defined as 0 degrees Celsius, and the boiling point of water is defined as 100 degrees Celsius at standard atmospheric pressure.The Celsius scale is an integral part of the International System of Units (SI), which is the modern metric system used for scientific and everyday measurements.In certain scientific and engineering fields, such as thermodynamics, the Kelvin scale (symbol: K) is also used as an absolute temperature scale but the SI unit of temperature is Celsius.

Think about what you already know. Why might two objects be affected differently if the same strength force is exerted on them?
Answers
Answer:Explanation:
If the same strength force is exerted on two objects, but the objects have the different masses, the object with less mass will have a greater change in velocity. ... Forces affect motion because they can change an objects motion.
The reason for two objects being impacted differently even a similar strength of the force is applied/exerted to them:
- Two objects might be affected differently on the application of a force of the same strength owing to the difference in their masses.
The second law of motion by Newton states that the rate of change of momentum of an object is directly proportional to the applied unbalanced force in the direction of the force.However, We know, Momentum = Mass × velocity.Hence, if the masses are different and the force applied is the same, the two objects will move with different velocities.

3. Use Newton’s Laws to explain why, when a 100Kg astronaut throws a 9Kg bowling ball forward in space, she moves backward but slower.
Answers
Answer:
An object in space that has no motion has to be shoved to move in the first place because of newton's first law of motion. A bowling ball will slow down and stop when rolled on a flat surface, like a street because of rolling friction which comes under Newton's first law of motion. When a 100Kg astronaut throws a 9Kg bowling ball forward in space, she moves backward but slower, this is because of Newton's third law of motion.Explanation:
This is due to Newton's first law of motion, explaining that an object in space that has no movement has to be moved to move in the first place. There is no external force or gravitational force in space, so the body can stay at rest and be forced to move first. Explaining why a bowling ball, like a street, can slow down and stop when rolled on a flat surface. This, again, is attributed to Newton's first law of motion. Due to rolling friction, it happens. The electrons on the surface of the ground in the atoms push against the electrons that touch the ground in the atoms on the surface of the ball as you roll a ball on the ground. A rolling ball stops when the surface on which it rolls opposes its motion. A ball rolling, due to friction, ceases.Explaining that when a 100 kg astronaut throws a 9 kg bowling ball forward in space, she travels backward but slower, due to Newton's third motion rule , which states that when force is applied, each body exhibits equal and opposite reaction. In this case, the astronaut's mass is greater, so the ball's acceleration will be less than the astronaut 's mass (since the body's mass is inversely proportional to the acceleration). Therefore, because of the reverse direction and slowly because of no gravitational force in space, the girl shifts backward while tossing the ball forward in space.Newton's Law of Motion -
FIRST LAW - The first law of Newton states that if a body is at rest or moving in a straight line at a constant speed, it will stay at rest or continue to travel at constant speed in a straight line unless it is acted upon by a force.
SECOND LAW - The second law of Newton is a quantitative explanation of the changes that a force can cause in a body 's motion. It states that the rate of change of a body's momentum in time is proportional to the force exerted on it in both magnitude and direction.
THIRD LAW - The third law of Newton notes that they apply forces to each other when two bodies interact, which are equal in magnitude and opposite in direction. Often known as the law of action and reaction, the third law is. In analyzing static equilibrium problems, where all forces are balanced, this law is essential, but it also applies to bodies in uniform or accelerated motion.
Hence , all the three explainations consist of newton's first and third laws of motion.

An observer is standing next to the tracks, watching a train approach. The train travels at 30 m/s and blows its whistle at 8,000 Hz as it approaches and then passes by the observer without slowing down. Assuming the speed of sound is 340 m/s, how much of a frequency change did the observer hear?
Answers
Answer:
The frequency heard by the observer will be "7351.35 Hz".
Explanation:
The given values are:
Source,
[tex]V_s=30 \ m/s[/tex]
Frequency of source,
[tex]F_s=8000 \ Hz[/tex]
Speed of sound,
[tex]C=340 \ m/s[/tex]
As we know,
⇒ [tex]F=(\frac{C+V_r}{C+V_s} )F_s[/tex]
Here,
[tex]V_r=0[/tex]
So that the formula will be:
⇒ [tex]F=(\frac{C}{C+V_s} )F_s[/tex]
[tex]=\frac{340}{340+30}\times 8000[/tex]
[tex]=7351.35 \ Hz[/tex]
