A typical male sprinter can maintain his maximum accelerationfor 2.0 s, and his maximum speed is 10 m/ s. After he reachesthis maximum speed, his acceleration becomes zero, and then he runs atconstant 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 straightline. 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?
