... Because friction is negligible, there is no change in the sled’s thermal energy. And, because the sled’s height is constant, its gravitational potential energy is unchanged as well. Thus the work-energy equation is simply ∆K = W. We can therefore find the sled’s final kinetic energy, and hence its s ...
