Question

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

Answer 1

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

Answer 2

Answer:

Given :-

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

To Find :-

• What is the potential energy.

Formula Used :-

To find potential energy we know that,

★ P.E = mgh ★

where,

• P.E = Potential Energy
• m = Mass
• g = Acceleration due to gravity
• h = Height

Solution :-

Given :

• Mass (m) = 4.3 kg
• Acceleration due to gravity (g) = 10 m/s²
• Height (h) = 1.3 m

According to the question by using the formula we get,

↦ P.E = 4.3 × 10 × 1.3

↦ P.E = 43 × 1.3

➠ P.E = 55.9 J

∴ The potential energy is 55.9 J .
