A. how does increasing the initial height of the skater affect the top speed of the skater?

b. how does increasing the initial height of the skater affect the height the skater rises to?

c. how does increasing the initial height of the skater affect total energy?

For the first one I think that depending on how high up you put the skater effects how fast/the velocity is.

For B I don't know

And for C I think that it depends on where you were to put it, if you put it somewhere down low, then it's energy would be really low compared to if you were to put the skater on a high ramp, the gravity pulling down on it would give it a greater force

Sorry I wasn't too helpful with it, did my best!:) And sorry if it's too late to use these for you

Explanation:

For A if you put the skater way up high when it came down all the gravity pulling down on the skater would cause it's/ there velocity to become greater because of the force pushing down on it (AKA Kinetic Energy)

b) phosphorus pentoxide

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
