A sled is pulled up to the top of a hill. At thetop of the hill the sled is released from rest and allowed to coastdown the hill. At the bottom of the hill the sled has a speedv and a kinetic energy E ( the energy due to the sled'smotion).The sled is pulled up a steeper hill ofthe same height as the hill described above. Howe will thevelocity of the sled at the bottom of the hill (after it has sliddown) compare to that of the sled at the bottom of the originalhill?a. the speed at the bottom is greater for the steeperhillb. the speed at the bottom is the same for both hills.c. the speed at the bottom is greater for the orignal hillbecause the sled travels further.d. there is not enough information given to say which speed atthe bottom is fastere. none of the above
