A \(50 \mathrm{~kg}\) sprinter, starting from rest, runs \(50 \mathrm{~m}\) in \(7.0 \mathrm{~s}\) at constant acceleration.

a. What is the magnitude of the horizontal force acting on the sprinter?

b. What is the sprinter's average power output during the first \(2.0 \mathrm{~s}\) of his run?

c. What is the sprinter's average power output during the final \(2.0 \mathrm{~s}\) ?
