Answer :
The work done by the crate to raise the barrel was found t be about 3000J.
How to calculate work done?
Work is a measure of the energy it takes to move an object; most often force times distance.
It is said that "things that don't move have no merit". Work done can be calculated by multiplying the force by the distance traveled as follows:
Work done = Force × distance
According to this question, a box of 1000N is raised to a height of 3.0m. The work done on the barrel is calculated as follows
W = 1000x3 = 3000J
so the work done for lifting the crate was found to be 3000J
