Question

Calculate the potential energy of a 60 kg student sitting in the top row of the bleachers, which are 4 meters from the ground.

Answer 1

Answer:

2400 J

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 = 60 × 10 × 4

We have the final answer as

2400 J
