Question

Calculate the gravitational potential energy of a 1,200 kg car at the top of a hill that is 42 m high.

Answer 1

Answer:

Gravitational potential energy = 493,920 J

Explanation:

Given:

Mass of car = 1,200 kg

Height = 42 m

Find:

Gravitational potential energy

Computation:

We know that;

Gravitational acceleration g = 9.8 m/s²

Gravitational potential energy = mgh

Gravitational potential energy = (1,200)(9.8)(42)

Gravitational potential energy = (11,760)(42)

Gravitational potential energy = 493,920 J
