The skater has potential energy of 7,056 joules.
How do you calculate the mass of an object that has a potential energy of 180 joules and rest at the top of a hill 15 meters from the ground?
The mass' approximate potential energy at four meters is 784 joules.
The potential energy, expressed in joules, is 196 times its height above ground, expressed in meters.
Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.

The mass' approximate potential energy at four meters is 784 joules.
The potential energy, expressed in joules, is 196 times its height above ground, expressed in meters.
Gravitational potential energy = mgh = 3 x 9.8 x 8 = 235.2 joules.
The formula for potential energy is PE = mgh (potential energy is mass times gravity times height). Gravitation is usually assumed to be 9.8 [m/sec2]. The assumption is probably that ground level is zero potential energy.
The ball's potential energy at 0.8 meters is 3.92 joules.
The object's potential energy is 6,664 joules.
The mass is 0.33kg
Potential energy = (weight) x (height) = (mass x gravity) x (height) = (742 x 9.8) x (5) = 36,358 joules(with respect to the ground)
A 1-newton book at 4 meters gains approximately 4 joules of potential energy.
The book's potential energy is 294 joules.
