Problem 14.9 The 700 N skier is schussing on a 25° slope. At the instant shown, he is moving at 20 m/s. The kinetic coefficient of friction between his skis and the snow is Mk = 0.08. Aerodynamic drag exerts a resisting force on him of magnitude 0.015v2, where v is the mag- nitude of his velocity. If he makes no attempt to check his speed, how long does it take for it to increase to 60 m/s?
