The cart was sitting still at the original's point for 5 seconds, then was moving with constant speed away from the origin in the positive direction with the speed of 20 m/s for 3 seconds, then made a stop for 2 seconds turned around and moved back to the origin with acceleration 2 m/s².

Calculate how far did the cart move in positive direction first? Draw velocity v/s time graph to present the motion of the cart during the whole time.
