Answer:

E = 8085 kJ

Step-by-step 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 :

E=mgh

Put all the values,

$E=1500* 9.8* 550\\\\E=8085000\ J\\\\or\\\\E=8085\ kJ$

So, the gravitational potential energy is 8085 kJ.
