Question

# A block has a mass of 1120 Kg. It is at the height of 10 m. How much gravitational potential energy does the block have?

- 1.098 Kg
- 10.98Kg
- 109.8Kg
- 1098Kg

Hint:

### If the mass is 1120 Kg, h is 10 m, and the GPE is 109.8 10^{3} Kgm^{2}/s^{2}.

## The correct answer is: 109.8Kg

- The gravitational potential energy GPE= mgh.
- m = 1120 Kg, h= 10 m.

GPE = mgh

= 1120 9.8 10

=109.8 10^{3} Kgm^{2}/s^{2}
