. How does the total energy of the pendulum change as it oscillates? Draw the graph 
for the first six oscillations.

as a function of time 
between the oscillation energy after 2 oscillations and the initial energy.
oscillates with a frequency

and hangs on a string with a length of 
. The hypnotist initially oscillates with the clock slowly with an amplitude of 
. Then he begins a forced oscillation such that the amplitude is equal to a quarter of the length of the string. At least how many oscillations does it take for this to happen if the hypnotist adds 
of energy with each oscillation? Assume that we are dealing with a simple pendulum.
