2. If you have a mass of 60 kg and you are standing
on a platform 5 m above the ground, what
is your gravitational potential energy?

2940 joules

Explanation:

Given that:

mass = 60 kg

Height of platform = 5 m

Gravitational potential energy GPE = ?

Recall that potential energy is the energy possessed by a body at rest. So, GPE is a product of your mass, acceleration due to gravity, g (9.8m/s^2) and the height involved.

So, Gravitational potential energy = mgh

GPE = 60kg x 9.8m/s^2 x 5m

GPE = 2940 joules

Thus, your gravitational potential energy is 2940 joules
