A mouse can scrawl with a velocity 2m/s on a stationary truck of rectangular shape. The truck is moving with constant speed 5m/s along a straight road. The points P Q B and C are the corners of the truck and A is midpoint of PQ .Now the mouse starts moving from point A and following the cyclic path through the edges if the truck, it reaches back to the point A. What is the displacement of mouse with respect to ground when it returns to point A ? Assume that the mouse moves with 2m/s w.r.t. truck throughout the motion and the dimension of the truck is 6m X 2m.
