Problem
Two athletes of equal mass cover the same distance on a straight track, but Athlete X reaches the finish line much sooner than Athlete Y.
(a) Using the idea of rate of doing work, explain qualitatively why Athlete X develops more power than Athlete Y even though both perform nearly the same amount of work.
(b) Other than time taken, state one factor that can cause the power developed by a runner to change and justify your answer briefly.
