Problem C4:
A simple pendulum of length n1 meters is let go from rest at an
angle of 60 degrees. The pendulum is on a strange planet with an acceleration
due to gravity of g=n2 meters/sec2. What is the speed of the
bob at the bottom of the pendulum where it is a maximum. If the speed
at the bottom is v=n3 meters/sec, What is n3?
