A hiker hikes in a straight line and maintains a constant velocity of +0.5 m/s. At time t=0.0 s, the hiker is 30 m from point A. What is the displacement from point A at 120 s?
60 meters, because he starts at point A and moves with a constant velocity of 0.5 m/s for 120s, 0.5x120=60 so the displacement is 60 meters, because the displacement is the distance between the starting point and the finishing point.
