Question

A 1800 kg car is parked at the top of a hill 4.7 m high. What is the gravitational potential energy of the car?

Answer 1

Answer:

Gracitational potential energy of the car is 84600J or 84.6KJ

Explanation:

Given that the formula of G.P.E is mgh. So use this formula to find gravitational potential energy :

G.P.E = mgh

m = 1800kg

g = 10m/s

h = 4.7m

G.P.E = 1800×10×4.7

= 84 600J (joules)

= 84.6KJ (kilo joules)
