3. An athlete pushes against an exercise machine with a force that varies with time according to F(t) = 1200 N (1 – k f), where k = 8 s² Also, the velocity of the athlete's legs acting in the same direction as the force acts according to v(t) = 7 m/s² t a. Create a computer generated plot of the power as a function of time. b. Find the maximum power the athlete generates and the time at which maximum power is generated.

Expert Solution
Step 1
(a)
Given -
F = 1200(1- kt2) N
Where k =8
So,
F = 1200(1- 8t2) N
Velocity (v) = 7t m/s
Now,
Power (P) = Force x Velocity = F x v
(P) = 1200(1- 8t2) x 7t
(P) = Watt
