The gravitational potential energy of Sean and the parachute at the top of the tower is $54,840~J$
We can find the gravitational potential energy at the top of the tower: $U_g = mgh$ $U_g = (68.0~kg)(9.80~m/s^2)(82.3~m)$ $U_g = 54,840~J$ The gravitational potential energy of Sean and the parachute at the top of the tower is $54,840~J$.
