Question

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

Answer 1

1762.04J

Step-by-step 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
