A ball of mass 0.700 kg is carefully balanced on a shelf that is 2.60 m above the ground. What is its gravitational potential energy

17.84 joules

Explanation:

A ball has a mass 0.700 kg

The height of the shelf is 2.60 m

g= 9.8

Therefore the gravitational potential energy can be calculated as follows

mgh

= 0.700 × 2.60 × 9.8

= 17.84 joules

Hence the gravitational potential energy is 17.84 joules
