1) A ball swinging at the end of a massless string, as shown in the figure, undergoes simple
harmonic motion. At what point (or points) is the magnitude of the ball's potential energy
a minimum? Assume A and D are the same distance away from C and C is the center of
the oscillation.
A) A and C
B) C
C) A and B
D) A and D
E) B.
2) If we double the frequency of a system undergoing simple harmonic motion, which of the
