A 3.0 kg body is at rest on a frictionless horizontal air track when a constant horizontal force →F acting in the positive direction of an x-axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in Fig. 7-25. The force →F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals. How much work is done on the body by the applied force →F between t = 0 and t = 2.0 s?
