Two runners are in a race. Both runners start at the same time. The first runner travels at a constant velocity of 6 m/s, while the second accelerates from rest at 4 m/s 2 to reach a maximum speed of 8 ms. How long does it take the second runner to catch up to the first runner? How far have they each travelled?
