Question

How high is a 32 kg box lifted if 960 J of work are done?

Answer 1

3.1m

Explanation:

Given parameters:

Mass of the box = 32kg

Work done = 960J

Unknown:

Height , h = ?

Solution:

The height through which the box must be lifted can be derived from the relationship between work done and potential energy applied.

      work done = mgh = potential energy

where m is the mass of the box

           g is the acceleration due to gravity

            h is the height of box

 

 make h the subject of the formula and substitute the parameters:

             h = $\frac{work done }{mg}$ = $\frac{960}{32 x 9.8}$

             h = 3.1m
