1. The problem statement, all variables and given/known data 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 38% . By what percentage would the sled's kinetic energy have increased if this force had pointed 62o above the +x axis? 2. Relevant equations The Work-Energy Theorem 3. The attempt at a solution So I get, that the kinetic energy is reduced by 35% . Correct answer: the kinetic energy increases by 18% .
