Question

A body of mass 10 kg is raised to a height of 4m above the ground . Calculate the energy possessed by the body .​

Answer 1

Answer:

400 joules

Explanation:

Given:

• Mass of the body = 10 kg

• Height to which the body is raised = 4 metres
• Gravity = 10 m/s²

To find :

Potential energy (in joules)

Potential energy = mgh;

Where:

m = mass of the body

g = gravitational force

h = height

So substituting the values,

Potential energy = 10×10×4

Potential energy = 100×4

Potential energy = 400 joules

The potential energy possesed by the body is equal to 400 joules
