For the
purpose we will use the following equation for potential energy:
U = m * g * h
In the
above equation, m represents the mass of the object, h represents the height of
the object and g represents the gravitational field strength (9.8 N/kg on
Earth).
When we
plug values into the equation, we get following:
U= 50kg * 9.8 N/kg *9m = 4410 J
