Two blocks are connected via a pulley, both blocks have a mass of 10.kg. One block rests on a horizontal surface and the other one hangs freely by a cord which passes over a pulley. Assume the cord does not stretch, ignore mass of pulley and cord, therefore acceleration is the same for both blocks and tension is the same for both blocks. The hanging block moves down so the block lying on the horizontal surface moves to the right. b. A 10.0 kg box slides down a 30.0 degrees incline at a rate of 0.40 m/s^2.
