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). answer the following question. friction and air resistance are so small they can be ignored. the sled is pulled up a higher hill that is less steep than the hill described above. how does the speed of the sled at the bottom of the hill (after it has slid down) compare to that of the sled at the bottom of the original hill? choose the best answer below.
