a sled with no initial velocity accelerates at a rate of 3.2 m/s squared down a hill how long does it take to sled to go 15 m to the bottom ​

Answers

Answer:

After 3.06seconds

Explanation:

Given that the following data are

acceleration a= 3,2m/s^2

distance s=15m,

time t=?  

Applying the formula for the equation of motion we have

s=ut+1/2at^2

we no initial velocity (u=0)

substituting our given values into the expression we have

15=0*t+1/2(3.2)t^2

15=1/2(3.2)t^2

15=3.2t^2/2

30=3.2t^2

t^2=30/3.2

t^2=9.375

Squaring both sides we have

t=√9.375

t=3.06seconds

It will take the sled 3.06 seconds to get to the bottom

Can an object experiencing constant acceleration change its direction of motion? Explain.

Answers

Answer:

Yes it can.

Explanation:

A object undergoing a constant acceleration has a constantly changing velocity. If the acceleration always points in the same direction as the velocity, the trajectory will be no different than if there were no acceleration, but in general acceleration will change the trajectory.

Explanation:

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity. Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling? Consider the "up" direction to be positive.

Which graph is it?​

Answers

Answer:

B

Explanation:

The only force acting on the block is gravity, so the block has a constant, negative acceleration. This means the velocity of the block is decreasing at a constant rate, so the answer is B, D, or E. Velocity is the rate of change of displacement, and answer choice B is the only one that has a displacement graph that matches that idea.

Answer: Graph B here correctly describes the displacement and velocity of the object during the time the object is falling. Option B is correct.

It is given that the mass of an object is dropped from height 'h' above the ground and "up" direction is taken to be positive.

It is required to find the graph which describes the displacement and velocity of the object during the time the object is falling.

Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling?

If any body falls freely towards the ground, then its acceleration is decreasing constantly with respect to time. That means velocity of an object will also be decreased as shown in graph B. Also we know that velocity is the rate of change of displacement.

As it is given in question that up direction is positive then it is also considered that downward be negative means decreasing.

Therefore, both the quantities are decreasing. So graph B correctly describes the displacement and velocity of the object during the time the object is falling.

A freeway exit curves with a radius of 30 m and a posted speed limit of 17.5 m/s. What is your radial
acceleration if you take this exit at the posted speed?

Answers

Answer:

10.21m/s²

Explanation:

Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:

a(r) = v²/r

Where a(r) = radial acceleration

v = velocity

r = radius of the circular path

According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;

a(r) = v²/r

a(r) = 17.5²/30

a(r) = 10.208333

a(r) = 10.21m/s²

Introduction This section describes the principles and concepts related to the experiment. It is used to help the person reading your report to understand the information that serves as foundation for the experiment. It also includes a brief statement about the purpose of the lab. Example: Surface tension is the attractive force exerted upon the surface molecules of a liquid by the molecules beneath. Water has a high surface tension because there are strong attractive forces between water molecules. Adding surfactants, like soap, can reduce the surface tension of a liquid. The purpose of the experiment was to determine the effect of soap on the surface tension of water.

Answers

Answer:

See explanation

Explanation:

It is a common observation that when water drops on a clean glass surface, it appears as little bags of water.

Surface tension makes water surface act like a stretched elastic skin bag.

Surface tension is caused by attractive forces between the molecules at the surface and the molecules in the bulk of a liquid. Remember that the forces of cohesion between water molecules are very strong.

When surfactants such as soap are added to water, the surface tension of water is decreased, hence the experiment.

ANSWER

Mass: The resistance of an object to acceleration, size-dependent

Volume: The amount of space an object occupies

Boiling point: The temperature at which a liquid boils and turns to vapor.

Melting point: The temperature at which a solid melts and turns to liquid

Density: Size-independent

Solubility: The ability of a substance (solvent) to dissolve when placed in a liquid (solute)

Magnetism: Size-dependent

EXPLANATION:

Mass: the more mass something has, the harder it is to accelerate. This is somewhat intuitive, but is also demonstrated in newton's third law. It's size-dependent because for an object of a given density, the size (volume) will change the mass.

Volume: big objects take up more space. If you put an apple in bucket filled to the brim with water, a little water will splash out, because the apple is now occupying the space that the water used to, but if you put in a watermelon, a lot of water will splash out, because the watermelon is taking up even more space.

Boiling point: when a liquid gets too hot, it will change to gas (example: water to steam)

Melting point: when a liquid gets too cold, it will change to a solid (example: water to ice)

Density: how much mass there is in a given volume. A sphere made of lead will have more mass than a sphere made of wood, even if they are the same size. Size-independent because a big lead sphere has the same density as a small lead sphere, they just have different masses.

Solubility: some substances dissolve in certain solvents, other's don't.

Magnetism: size-dependent because a bigger magnet is stronger than a smaller one if they are identical in every other way. More space means more domains means a stronger magnet.

What's your favorite
family/cultural tradition? Why is this tradition your
favorite?

Answers

Answer:

Every summer we go and work at a summer camp. My whole family loves it, and it's something that always brings us closer.

Explanation:

Christmastime is without a doubt my favorite time of year, not because of Christmas itself, but because of the atmosphere leading up to it. I've always felt this way, and I believe that is because of my grandmother. My Nanny was the same way. She loved Christmas, and went all out every year. Her house was put in the local newspaper several times because of all the lights and decorations she put up. If only they could have gone inside the house!

Anyway, there are a lot of things I did with my grandma around Christmas, and if I had been asked my favorite tradition when I was a young child, I might have said “decorating,” or “making Christmas treats,” but looking back, it is what we would do every Christmas Eve.

Christmas Eve is last-minute shopping day for the adults of my family, and the only shopping day for the kids. I would head out with my dad in the morning and shop, then go to lunch with my grandpa, and then finally, I would go with my grandma. We would shop a little, and then she would always buy some fake poinsettias. We would then travel to a tiny cemetery that seemed like an hour away back then, and I would walk with her to her father's grave.

Even as a young child, I felt the emotions in the air when we visited his grave. She never cried or showed any signs of sadness, but I could just sense how special the moment was to her. When her mother passed away in 2013, we went to visit both of them, and the atmosphere only intensified.

My grandma died in March of 2015 after a long battle with cancer. Every Christmas Eve, I buy the most beautiful poinsettias I can find, and visit her grave. It's always freezing outside, being December, but I stand for a few minutes, remembering, and then I get back in my car and head home.

My fondest tradition isn't the most fun, or the most festive. It's the one that means the most to me. One day, I hope I can take my children or grandchildren with me, and I hope they'll feel everything that I felt.
