A sled with a child sliding down (from rest) at 14 degree hill has a mass of m=120kg. The length of the hill is 60 m and coefficient of kinetic friction between the surface ad the sled is .14. Once at the bottom of the hill the sled continues along the horizontal surface. How far will the sled travel along the horizontal surface? how long? and acceleration?
