Solved: A sled is being pulled across a horizontal patch
Chapter 6, Problem 6.94(choose chapter or problem)
A sled is being pulled across a horizontal patch of snow. Friction is negligible. The pulling force points in the same direction as the sleds displacement, which is along the x axis. As a result, the kinetic energy of the sled increases by 38%. By what percentage would the sleds kinetic energy have increased if this force had pointed 62 above the x axis?
