Question

An apple with a mass of 0.95 kilograms hangs from a tree branch 3.0 meters above the ground. what is the potential energy of the apple?

0.28j
2.8j
28j
280j

Answer 1

285 J

Step-by-step 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 = 0.95 × 10 × 30

We have the final answer as

285 J

Hope this helps you
