Using the graph shown,
A) Draw the velocity vs. time graph given the position vs. time graph of a pendulum.
B) What is the period of the motion?
C) Angular frequency.
D) Assuming this is an Ideal pendulum with a mass of 2kg and where all the weight is located at the bottom what, is the length of the string ?
E) If the mass is decreased to 1kg describe and explain how the period changes?
