A 500 gram mass is used as a pendulum bob so that itforms a pendulum that is 2.0000 metres long.The pendulum isdisplaced from its rest position by an angle of 10.000degrees.
a) How high is the pendulum bob above its originalposition?Draw a digram in which variables are clearlyillustrated.
b) What is the magnitude of the energy that the pendulum bobpossesses in this position?
c) What is the maximum speed of the pendulumbob when it is released?
