A sled is pulled up to the top of a hill. The sketch above indicates the shape of the hill. At the top of the hill the sled is released from rest and allowed to coast down the hill. At the bottom of the hill the sled has a speed v and a kinetic energy E (the energy due to the sled's motion). Friction and air resistance are so small they can be ignored. The sled is pulled up a steeper hill of the same height as the hill described above. Compare the kinetic energy (energy of motion) of the sled at the bottom for the original hill and the steeper hill in the previous problem. Choose the best answer below. The kinetic energy of the sled at the bottom is the same for both hills. The kinetic energy of the sled at the bottom is greater for the steeper hill. The kinetic energy at the bottom is greater for the original hill. There is not enough information given to say which kinetic energy is greater. None of these descriptions is correct.

PLEASE ANSWER ASAP!!!!!!!!!!

A sled is pulled up to the top of a hill. The sketch above indicates the shape of the hill. At the top of the hill the sled is released from rest and allowed to coast down the hill. At the bottom of the hill the sled has a speed v and a kinetic energy E (the energy due to the sled's motion). Friction and air resistance are so small they can be ignored. The sled is pulled up a steeper hill of the same height as the hill described above. Compare the kinetic energy (energy of motion) of the sled at the bottom for the original hill and the steeper hill in the previous problem. Choose the best answer below. O The kinetic energy of the sled at the bottom is the same for both hills. The kinetic energy of the sled at the bottom is greater for the steeper hill. The kinetic energy at the bottom is greater for the original hill. There is not enough information given to say which kinetic energy is greater. None of these descriptions is correct.
