1. A skier of mass 42.1 kg starts at the top of a hill with a speed of 5.30 m/s. The hill is angled at 27.20 and is 11.2 m high. The skis have jets that do 575 J of work. The coefficient of kinetic friction between the skis and the snow is 0.100. When the skier gets to the bottom of the hill, the skier slides on horizontal ground that is frictionless. A spring with a spring constant of 145 N/m is 1.0 m from the bottom of the hill to stop the skier. A) How fast is skier moving at the bottom of the hill? B) How far is the spring compressed to stop the skier?
