A runner accelerated from rest at x0 = 0m with a constant acceleration 2.0 m/s2 for 2.0 s and then kept running with his constant velocity for an additional 8.0 s. Assume that the runner moved in a straight line. a) How far did the runner move? b) What is his average speed? c) plot the motion graph of the position x(t), the velocity v(t), as well as the acceleration a(t) for the runner. Please mark on the motion graph the exact values of x(t), v(t), and a(t) at t = Os, 2s and 10s.
