A body weighing 800 g has a potential energy of 60 kJ. How high is the body?

Since the body has potential energy, then
Ep = mgh
Let’s convert the mass to kilograms:
800/1000 = 0.8
Let’s convert kJ to J:
60 * 1000 = 60,000
Free fall acceleration (g) is constant and equal to 9.8
Let’s go back to the formula:
60,000 = 0.8 * 9.8 * h
h = 60,000 / 0.8 * 9.8 is approximately equal to 7653 meters
Answer 7653m
