A 45 kg box is sitting on a window ledge 2.0 m above the ground. What is the potential energy of the box?

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 45 × 10 × 2

We have the final answer as

Hope this helps you

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

so what is the problem with your lab report and whats the subject of the lab report? i will you
