Referenced to the floor, 0.5 kg of mass 2 meters above it has(M) (g) (h) = (0.5) (9.8) (2) = 9.8 joulesof gravitational potential energy
Potential Energy is defined by the equation Ep = mgh so: Ep = mgh Ep = (0.5)(9.81)(2) Ep = 9.81 Joules
P.E=mgh P.E=20*9.81*0.5 P.E=98.1 J
The skater has potential energy of 7,056 joules.

The potential energy, expressed in joules, is 196 times its height above ground, expressed in meters.
Gravitational Potential Energy.
Calculate the potential energy at its highest point. Don't use the 6 meters above the ground - use the 5 meter difference from the lowest point. This part of the potential energy gets converted into kinetic energy, when the pendulum is at its lowest point. Just assume that all the potential energy (for the 5 meters difference) get converted into kinetic energy.Calculate the potential energy at its highest point.

Calculate the gravitational potential energy between 5 m and 2 m above the ground. If you ignore air resistance, all of that potential energy will be converted to kinetic energy, so that's the answer.
