A 4.3 kg monkey swings from one branch to another 1.3 m higher. What is the change in potential energy?

Given

A 4.3 kg monkey swings from one branch to another 1.3 m higher

To Find

The change in potential energy

Solution

We know that

PE = mgh

Here

PE = Potential Energy

m = Mass

g = Accl. due to gravity

h = Height

According to the question

We are asked to find the change in potential energy

Therefore

We must find "PE"

Given that

A 4.3 kg monkey swings from one branch to another 1.3 m higher

Hence

m = 4.3 kg

h = 1.3 m

We know that

g = 10 m/s2

Substituting the values

We get

PE = 4.3 x 10 x 1.3 J

PE = 55.9 J
