Homework Statement
A skier with a mass of 45 kg is standing at the top of a 45 m hill.
· Calculate the gravitational potential energy of the skier when she is standing at the top of the hill
· Calculate the kinetic energy of this skier at the bottom of the hill, where she has a speed of 7.2 m/s
· Explain why the kinetic energy of the skier at the bottom of the hill is not equal to the gravitational potential energy of the skier at the top of the hill
