I am not sure if my answer is right, could you check it for me please? A sled is pulled up to the top of a hill. The sketch belowindicates the shape of the hill. At the top of the hill the sledis released from rest and allowed to coast down the hill. Atthe bottom of the hill the sled has a speed v and a kineticenergy 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 thehill described above. How will the velocity of the sled at thebottom of the hill (after it has slid down) compare to that ofthe sled at the bottom of the original hill? Choose the bestanswer below.The speed at the bottom is the same for both hills.O The speed at the bottom is greater for the steeper hill.O The speed at the bottom is greater for the original hill becausethe sled travels further.O There is not enough information given to say which beed atthe bottom is faster.O None of these descriptions is correct.

Given data: A sled is pulled up to the top of a hill At bottom the kinetic energy is E and speed is v Air resistance and friction force are ignored Required: The velocity of the sled at the bottom of the hill after slid down compare to at the bottom of the original hillAccording to conservation of energy The total energy of the system is remains constant. The total mechanical energy is the sum of the kinetic energy and potential energy. The gravitational potential energy is given by PE = mgh Here g = acceleration due to gravity, constant The both initial and final position are at same height so the potential energy is same.The potential energy of the sled remains same so the kinetic energy also remains same to conserve total mechanical energy. The kinetic energy is given by KE = 12mv2 The kinetic energy is directly proportional to the square of the speed of the sled The kinetic energy is same so the speed at the bottom is same for both hills
