1. You are standing on a big spring in an elevator. The elevator is accelerating downward with acceleration a = 2.50m/s2 and the spring is compressed. a) Draw a free body diagram to indicate all the forces on you. b) If your mass is 55.0kg and the spring constant k is 2400 N/m, how much is the spring compressed?

1. You are standing on a big spring in an elevator. The elevator is accelerating downward with acceleration a = 2.50m/s2 and the spring is compressed. a) Draw a free body diagram to indicate all the forces on you. b) If your mass is 55.0kg and the spring constant k is 2400 N/m, how much is the spring compressed? A boy of mass 45 kg runs into an ice-skating rink in street shoes and begins a smooth slide. He starts with a spee- of 6.3 m/s and cones to a stop after sliding for 2.4 s. What is the coefficient of kinetic friction of his shoes on ice? 2.
