A typical male sprinter can maintain his maximum acceleration for 2.0 s and his maximum speed is 10m/s . After reaching this maximum speed, his acceleration becomes zero and then he runs at constant speed. Assume that his acceleration is constant during the first 2.0 s of the race, that he starts from rest, and that he runs in a straight line. How far has the sprinter run when he reaches his maximum speed? What is the magnitude of his...

A sprinter in a 100m race accelerates from rest at a rate of 5.0m/s^2. She maintains this acceleration for a period of 6.0s. Once she has reached her top speed, she continues to run at her top speed for the rest of the race. Q. calculate the total time take for the sprinter to run the 100m race. - how do I get the time while accelerating and time while at constant velocity? Could you please explain how EASY and...
