an olympic bodybuilder lifts a 1325 kg weights a vertical distance of 2.5m off the ground. What potential energy do the weights have now?
A)34,462.5 J
B)31,462.5 J
C)33,462.5 J
D)32,462.5 J
The potential energy of an object can be calculated using the formula:
Potential Energy = mass × gravity × height
Given:
mass = 1325 kg
gravity = 9.8 m/s^2 (acceleration due to gravity)
height = 2.5 m
Potential Energy = 1325 kg × 9.8 m/s^2 × 2.5 m
Potential Energy = 32,462.5 J
So, the potential energy of the weights is 32,462.5 J.
The correct answer is D) 32,462.5 J.
