![Problem 3 - Work
At the top of a pole vault, an athlete actually can do work pushing on the pole before releasing it.
Suppose the pushing force is that the pole exterts back on the athlete is given by
F(x) = kjx – k2a² ,
where ki = 150 N/m and k2 = 190 N/m² acting over a distance d = 0.2 m. How much work is
