Question

What is the Gravitational Potential Energy of a 30kg block resting 5m above the ground?

O 150 J
O 1500 )
O 6J
O 60)

Answer 1

1470J

Step-by-step explanation:

Given parameters:

Mass of the block = 30kg

Height = 5m

Unknown:

Gravitational potential energy = ?

Solution:

The Gravitational potential energy of body is due to its position above the ground level.

Gravitational potential energy = mass x acceleration due to gravity x height

So;

Gravitational potential energy = 30 x 9.8 x 5 = 1470J
