Two of your friends are bungee jumping from Beta Bridge. After the initial fall and rebound, each jumper bounces up and down as a harmonic oscillator—a mass on the end of spring. The period of the oscillator is the time between successive bounces. One friend weighs twice as much as the other. Since they use the same bungee cord for their jumps,
A. the two friends will have the same period, regardless of how high they bounce.
B. the heavier friend will have a longer period than the lighter friend.
C. the two friends will have the same period, as long as the height of their bounces are the same.
D. the heavier friend will have a shorter period than the lighter friend.
