Suppose the diver at the top of a 9 m high platform has a mass of 50.0 kg. Calculate her potential energy relative to the ground. Answer in Joules.

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
