1. The problem statement, all variables and given/known data A 74.5 kg snowboarder heads down a 16.0° hill that has a height of 78.4 m. If the hill is assumed to be frictionless and there is horizontal wind with a force of 93 N acting against the snowboarder, find the speed of the snowboarder as they reach the bottom of the hill using work and energy. 2. Relevant equations W = FΔd Ep = mgΔy Ek = 1/2mv2 3. The attempt at a solution So far, I tried calculating potential energy at top: Ek = mgΔy = (74.5)(9.8)(78.4) = 57,239.84 J Work done by wind: W = FΔd = (93N)(78.4/sin16.0°) = 26,452.14753 J Then, I subtracted work done by wind from potential energy, then used the kinetic energy to solve for final velocity. What am I doing wrong?
