Answer to Question #168003 in Electricity and Magnetism for Matty

Question

A 6.0 kg object that is 3.0 m from the surface of the Moon has 28.8 J of gravitational potential energy. What is the value of g?

(Gravitational field strength/Gravitational acceleration)

Stuck trying to reverse logic this problem... If anyone has any steps using Eg=mgh I would appreciate it.

Answer 1

The gravitational potential energy:

$$E=mgh\\28.8=(6)(3)g\\g=1.6\frac{m}{s^2}$$
