A solid block of mass 40.0 kg starts from rest and slides down a rough surface with a length of 10.0 m where the coefficient of friction is uk = 0.150. The surface is inclined at 55.0. After sliding 10.0 meters down the incline it slides onto a flat surface with kinetic coefficient of friction of 0.250 moves 5.00 m. It then hits a spring with a spring constant of ks = 300.0 N/m.
