Question

A crate weighing 2400 N is lifted by a crane

to a platform 5.2 m above the ground. What

is the gravitational PE of the crate?

Answer 1

12,480Joules

Explanation:

GPE = mass * acceleration due to gravity * height

Since Force = mass * acceleration due to gravity

GPE = Force * Height

GPE = 2400 * 5.2

GPE = 12,480Joules

Hence the gravitational PE of the crate is 12480Joules
