Answer 2

Given,

The mass of a body is 32 kg and it is lifted to a height of 8 m above the ground.

To Find,

The gravitational potential energy.

Solution,

We know that:

Mass (m) = 32 kg

Height (h) = 8 m

Gravity (g) = 10m/s²

Gravitational potential energy $P_e$ = m x g x h

Substituting the values,

$P_e$ = 32 x 8 x 10 = 2560 J.

Therefore the gravitational potential energy of the body is 2560 J.
