What is the gravitational potential energy of a 1500-kg truck resting on top of a 550-m hill on earth?( earth’s gravitational pull is 9.8m/s2).

E = 8085 kJ

Explanation:

Given that,

The mass of a truck, m = 1500 kg

Height, h = 550 m

We need to find the gravitational potential energy of the truck. It can be calculated as follows :

Put all the values,

So, the gravitational potential energy is 8085 kJ.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
