(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Gravitational Potential Energy

1. The problem statement, all variables and given/known data

Calculate the change in potential energy of a 77.2-kg man when he takes an elevator from the first floor to 24th floor, if the distance between floors is 4.05 m.

2. Relevant equations

Ug = mgy

3. The attempt at a solution

Ug = (77.2kg)*(9.81m/s^2)*(24*4.05m) = 73612.67N*m

What am I doing wrong??
