Q1. A girl on a sled coasts down a hill. Her speed is 7.0m s while she reaches level ground at the bottom. The coefficient of kinetic friction between sleds runners and the hard, icy snow is 0.05, and the girl and sled together weigh 645N. how far does the sled travel on level ground before coming to rest?

Q2. A 200, 47.0 cm-diameter turntables rotate on frictionless bearings at 70. A 24.0 block sits at the center of the turntable. A compressed spring shoots the block radically outward along the frictionless groove in the surface of turntable.
