... Yes - you just need to know how much of the initial energy was lost, which you can figure out from the height. Then, you use the kinetic energy formula to determine its velocity as in part d. For example, if the nickel fell 1.5 meters, it would only have 0.025 Joules of stored energy left; the kinet ...
