A 58 kg counterweight on a trebuchet is raised to a height of 3.1 meters. Calculate how much potential energy it has

1762.04J

Explanation:

Given parameters:

Mass of counterweight  = 58kg

Height  = 3.1m

Unknown:

Amount of potential energy  = ?

Solution:

The potential energy of a body is the energy due to the position of the body.

It is given as:

 Potential energy  = mass x acceleration due to gravity x height

So;

 Potential energy  = 58 x 9.8 x 3.1  = 1762.04J

c, 1a hope this

what is the question because that is not a question.
