A sled is being pulled across a horizontal patch of snow. Friction is negligible. The pulling force points in the same direction as the sled's displacement, which is along the +x axis. As a result, the kinetic energy of the sled increases by 43.6 percent. By what percentage would the sled's kinetic energy have increased if this force had pointed 65.2 ° above the +x axis?
