R is the radius of speed curvature of the turn, g is the acceleration due to gravity, and μs is the coefficient of static friction.

θ is the angle of banking. For no slippage to occur even when the contribution of the frictional force in the centripetal force is not considered, we ignore the effect of friction and get the Time. Well, if the radius must be a single measurement, then the turn will be perpendicular.

Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the shuttlecock when it hits the ground

Answers

The acceleration is still -9.81 m/s2, and the instantaneous velocity of the shuttlecock when it hits the ground is [tex]V_{int}[/tex] = [tex]\sqrt{U^{2} + 19.6H }[/tex]

Acceleration is determined as the rate of change of velocity of an object with respect to time. Acceleration is represented by the SI unit is meter per second squared (m/[tex]s^{2}[/tex]). Acceleration is denoted by "a".

Instantaneous velocity is the rate of change of position for a time interval which is almost zero (very small). The magnitude of the instantaneous velocity is instantaneous speed. It is measured by using SI unit m/s.

Mathematically, the equation for acceleration is:

a =  [tex]v\frac{dv}{dt}[/tex]

ah = [tex]v^{2}[/tex] - [tex]u^{2}[/tex]

Where the acceleration is still -9.81 m/s2

Hence, [tex]v^{2}[/tex] - [tex]u^{2}[/tex] = 2 (-9.81) * -H

Therefore, [tex]v_{int}[/tex] = [tex]\sqrt{U^{2} + 19.6H }[/tex]

Answers

The distance between the Naval Navigator and the sunken cargo was found to be 2175 m by using sonar with 120kHz frequency and a wavelength of 3mm.

What is the purpose of sonar?

Sonar is largely used by NOAA scientists to create nautical charts, find underwater navigational hazards, find and map things on the bottom like shipwrecks, and map the actual seafloor. Sonar comes in active and passive varieties.

Speed of sound in water  =1450m/s

Time lag between transmission and reception of Sonar waves =3 s

sound waves travel a distance is twice the distance between the navigator and cargo (2S) in this time lag.

A 2.5 kg block is initially at rest on a horizontal surface. A horizontal force of magnitude 6.0 N and a vertical force are then applied to the block (Fig. 6-17). The coefficients of friction for the block and surface are ms 0.40 and mk 0.25. Determine the magnitude of the frictional force acting on the block if the magnitude of is (a) 8.0 N, (b) 10 N, and (c) 12 N.

Answers

Kinetic friction force, or f k = k F N = 3.1N, is the amount of frictional force acting on the block.

Static friction is the friction that exists between two systems when they are in contact and immobile with respect to one another. Kinetic friction is the term for the resistance that exists between two systems while they are in contact and moving in relation to one another.

Calculation:

Either static or kinetic friction We decide on +x right and +y up. Applying Newton's second law to these axes:

F−f=ma

 P+F n −mg=0

where F=6.0 N and m=2.5 kg is the mass of the block.

(a) P=8.0 N in this scenario results in

          F N =(2.5kg)(9.8m/s 2 )–10N=14.5N.

This implies ,fs, max =μ s F N=6.6N, which is larger than the 6.0N rightward force. The block, which was previously at rest, stays in place as a result.

Putting a = 0

f=P=6.0 N is the static friction force that results from plugging the first of our equations above.

(b) With P=10 N in this instance, the normal force is

This suggests that, fs, max = s F N =5.8N, which is smaller than the 6.0 N rightward

force, which causes the block to move. Therefore, we are working with kinetic data instead of static data.

Eq. reveals that friction is f k = k F N =3.6 N.

(c) In the last scenario, P=12 N results in FN=12.5 N and fs, max = s F N = 5.0N.

which (as expected) is less than the 6.0 N rightward force. Thus, the block moves. The kinetic friction force, then, is f k =μ k F N =3.1N.

two blocks are connected by a string of negligible mass that passes over massless pulleys

Answers

If two blocks are connected by a string of negligible mass that passes over massless pulleys, the system can be analyzed using the principles of Newton's second law and the conservation of energy.

What is Newton's second law? In this scenario, the net force acting on each block is the tension in the string, which is equal in magnitude for both blocks. Therefore, if the blocks have different masses, they will have different accelerations. In this scenario, the mechanical energy of the system is the sum of the gravitational potential energy and the kinetic energy of the blocks. If the pulleys are massless and frictionless, then the mechanical energy of the system will be conserved.In summary, the two blocks will move together with the same acceleration if the pulleys are massless and frictionless.

Using the principle of conservation of energy and the final height the golf ball reaches after bouncing, determine the theoretical speed with which the ball must have left the floor (i.e on its way back up).

Mass: 0.0453kg
Initial height: 1m
Initial potential energy: 0.444J
Final height: 0.61m
Final potential energy: 0.271J
Efficiency: 61.0%

Answers

Answer:

2.58 m/s

Explanation:

To determine the theoretical speed at which the golf ball must have left the floor, you can use the principle of conservation of energy, which states that the total energy in a closed system remains constant. In this case, we can use the fact that the ball's potential energy changes as it rises and falls.

First, we know that the efficiency of the ball is 61.0%, so we can assume that 39% of the energy is lost as heat, sound, etc. We can calculate the initial kinetic energy (Ei) of the ball as:

Ei = Efficiency * (Initial Potential energy - Final Potential energy)

Ei = 0.61 * (0.444 - 0.271) = 0.119J

Now, we can use this value to calculate the velocity (Vi) of the ball as it left the floor, by using the equation of kinetic energy:

Ei = 0.5 * m * Vi^2

Where:

m = mass of the ball = 0.0453 kg

Vi = velocity of the ball when it left the floor

By substituting the values in the equation we get:

0.119 = 0.5 * 0.0453 * Vi^2

Solving for Vi:

Vi = sqrt(0.119 / (0.5 * 0.0453))

Vi ≈ 2.58 m/s

So, the theoretical speed with which the ball must have left the floor is approximately 2.58 m/s

Keep in mind that this is a theoretical speed and there may be a variance with real-world observations.

what's the average speed of a bike rider who rides for 3 hours at 40 km/hr and the 2 more hours at 50 km/hr

Answers

The average speed of a bike rider who rides for 3 hours at 40 km/hr and two more hours at 50 km/hr can be calculated by adding the total number of kilometers ridden and dividing it by the total time taken.

In this case, the rider has ridden for a total of 5 hours and has covered a total of 290km (3×40 + 2 × 50). Therefore, the average speed of the rider is 58km/hr (290/5).

Average speed can be defined as the rate at which an object covers a given distance over a given period. It is usually measured in kilometers per hour (km/hr), meters per second (m/s), or miles per hour (mph).

Average speed is calculated by dividing the total distance traveled by the total time taken. In this case, the rider has ridden for a total of 5 hours and has covered a total of 290km (3 × 40 + 2 × 50).

Explanation:

Given;

weight of the bronze statue, F = 2400 N

width of the bronze base, w = 1 m

length of the bronze base, l = 4 m

The area of the bronze base = l x w

                                                = 4 x 1

                                                 = 4 m²

The pressure exerted by the bronze on the floor is calculated as;

P = F/A

P = 2400/4

P = 600 N/m²

Therefore, the pressure exerted by the bronze on the floor is 600 N/m²

What is the mass of a softball if it hit the catcher's glove traveling at
48.7 m/s2 and struck with a force of 51.3-Newton?

Answers

Answer:

To solve this problem, you can use the formula F = ma, where F is the force applied to an object, m is the mass of the object, and a is the acceleration of the object. In this case, the force applied to the object is 51.3 newtons and the acceleration of the object is 48.7 m/s2. So, you can set up the equation like this:

51.3 newtons = m x 48.7 m/s2

To solve for the mass of the object, you can divide both sides of the equation by 48.7 m/s2:

51.3 newtons / 48.7 m/s2 = m x 48.7 m/s2 / 48.7 m/s2

This simplifies to:

1.05 kg = m

So, the mass of the softball is approximately 1.05 kilograms.
