Atypical 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 magni- tude of his average velocity for a race of these lengths:
(i) 50.0 m;
(ii) 100.0 m;
(iii) 200.0 m?
