BIO A typical male sprinter can maintain his maximum acceleration for 2.0 s and his maximum speed is 10 m> s. After he reaches 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. (a) How far has the sprinter run when he reaches his maximum speed? (b) What is the magnitude of his average velocity for a race of these lengths: (i) 50.0 m; (ii) 100.0 m; (iii) 200.0 m?
