65.0kg Jimmy B. was skiing in the Mountains. He starts, fromrest, at the top of a 15.0m stretch tilted 35.0° below thehorizontal. For the first 2.00m of the 15.0m stretch, he applies aforce of 250.N, parallel to the stretch. At the bottom of thestretch, he is moving at 13.0 m s . What was the coefficient ofkinetic friction, between the undersides of his skis and the snow,as he went down the 15.0 stretch? Note: This problem is intended tobe solved using Energy methods, not kinematical equations.
