Homework Statement
A sled is being pulled across a horizontal patch of snow. Friction is neglibile. 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 38 percent. By what percent would the sled's kinetic energy have increased if the force had pointed 62 degrees above the +x azis?
