An Olympic bodybuilder lifts a 1325 kg weight a vertical distance of 2.5 m off the ground. What potential energy do the weights have now?
a
32,462.5 J
b
33,462.5 J
c
34,462.5 J
d
31,462.5 J
c. 34,462.5 J
The potential energy is calculated as PE = mgh, where m is the mass (1325 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height (2.5 m).
PE = 1325 kg * 9.81 m/s^2 * 2.5 m = 34,462.5 J
