During your winter vacation, you enter a "dogsled" race across a frictionless frozen lake, in which the sleds are pulled by students instead of dogs. To get started, you pull the sled (mass m=50 kg) with a force of F=100 N at θ = 30o above the horizontal. The sled moves S = 30.0 m, starting from rest. Assume that there is no friction. (1) What is the final kinetic energy of your sled? (select the closest values)
