    a 48 kg person is sled-riding down a hill that is 4.6m high. starting at the top with the speed of 3.1m/s the sled reaces down with the speed of 7.6m/s determine the distance (Ef-E0) between the final and initial total mechanical energy

    Is it just asking for the difference in kinetic energy at the top and at the bottom? That is 1156J. Is the 7.6m/s the speed at the bottom?
