15. Pendulum How does a pendulum work?
Draw out the movement of the pendulum: where would it have maximum gravitational potential energy? Maximum kinetic energy? How does it demonstrate law of conservation of energy?

16. Pendulum

17. Practice
Standing on level ground, a person with a mass of kg jumps straight up into the air to a position where the person has gained 800J of gravitational potential energy. How high did the person leap?
A construction worker drops a 2.00 kg hammer from a roof. When the hammer is 50.0 m above the ground, it has a total mechanical energy of 1.88 x 103 J. Calculate the kinetic energy of the hammer.
