A father exerts a 2.51 102 N force to pull a sled with his daughter on it (combined mass of 77.9 kg) across a horizontal surface. The rope with which he pulls the sled makes an angle of 20.0° with the horizontal. The coefficient of kinetic friction is 0.200, and the sled moves a distance of 7.41 m.
