Question: Let the mass of the sled be m and the magnitude of the net force acting on the sled be Fnet . The sled starts from rest. Consider an interval of time during which the sled covers a distance s and the speed of the sled increases from v1 to v2 . We will use this information to find the relationship between the work done by the net force (otherwise known as the net work) and the change in the kinetic energy of the sled. Use W = F s cos (theta) to find the net work Wnet done on the sled. Express your answer in terms of some or all of the variables m ,v1 and v2 .
