The potential energy of an object is given by the formula:
Potential Energy = mass * gravity * height
where mass is the mass of the object, gravity is the acceleration due to gravity, and height is the vertical distance the object is lifted.
Here, the mass lifted is 1325 kg, the height lifted is 2.5 m, and the acceleration due to gravity is 9.8 m/s^2.
So, the potential energy of the weights is given by:
Potential Energy = 1325 kg * 9.8 m/s^2 * 2.5 m
= 32,512.5 J
Therefore, the potential energy of the weights after being lifted 2.5 m off the ground is 32,512.5 J.
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?
