You are on a pogo stick bouncing up and down. (If you don’t know what a pogo stick is, please ask someone.) The force from the ground on the bottom of the pogo stick is Ngp(y)=F0(1-y/h) with y being your position (y = 0 at your lowest point), F0 = 921 N, and your maximum height h = 0.8 m. The bottom of the pogo stick stays in contact with the ground until you are at your maximum height when the bottom just barely comes off of the ground. Using the pogo stick as the system, what is the work done by the ground on the pogo stick as you move from y = 0 m to y = 0.32 m.

Question

You are on a pogo stick bouncing up and down. (If you don’t know what a pogo stick is, please ask someone.)
The force from the ground on the bottom of the pogo stick is


Ngp(y)=F0(1-y/h)


with y being your position (y = 0 at your lowest point), F0 = 921 N, and your maximum height h = 0.8 m. The
bottom of the pogo stick stays in contact with the ground until you are at your maximum height when the bottom
just barely comes off of the ground.
Using the pogo stick as the system, what is the work done by the ground on the pogo stick as you move from y = 0 m
to y = 0.32 m.
