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. 34,462.5 J
b. 31,462.5 J
c. 32,462.5 J
d. 33,462.5 J
The potential energy of an object is given by the formula:
Potential Energy = mass * gravity * height
Where:
mass = 1325 kg
gravity = 9.8 m/s^2 (acceleration due to gravity)
height = 2.5 m
Substituting the given values into the formula, we get:
Potential Energy = 1325 kg * 9.8 m/s^2 * 2.5 m
= 32,462.5 J
Thus, the potential energy of the weights is 32,462.5 J.
The correct answer is c. 32,462.5 J.
