A person is pushing two carts that are connected with a metal bar so that the carts are moving at constant acceleration 0.20m/s2. The masses of the carts are 100 kg and 170kg, and the mass of the connecting bar is 60 kg. Assume that the friction forces are negligible. Also assume that you are pushing the lighter cart to the right.
