A 2-kg can containing 8 kg of water is initially stationary I Fig. a i. The center of mass of the "object" consisting of the cart and water is at x = 0. The cart is subjected to the time-dependent force shown in Fig. b. where F = 5N and tn = 2 s. Assume that no water spills out of the cart and that the horizontal forces exerted on the wheels by the floor are negligible.
