A 5 kg bowling ball hangs on a chain from a hook in the ceiling. The ball is pulled back and released from rest at a height 3 meters above the
ground and swings through it's lowest point just above the ground (we will call this height 0).

a. Calculate potential energy at the highest point.

b. Calculate kinetic energy at the highest point.

c. Calculate potential energy at the lowest point.

d. Calculate kinetic energy at the lowest point.

e. Calculate the velocity of the ball at its lowest point.
