Question: Three springs each hang from a ceiling with a stationary block attached to the lower end. The blocks (with m1> m2 > m3) stretch the springs by equal distances. Each block-spring system is then set into vertical SHM. Rank the masses according to the period of oscillation, greatest first.

Question:  A pendulum suspended from the ceiling of an elevator cab has period T when the cab is stationary. Is the period larger smaller, or the same when the cab moves:

1. Upward with constant speed
2. Downward with constant speed
3. Downward with constant upward acceleration
4. Upward with constant upward acceleration
5. Upward with constant downward acceleration a=g
6. Downward with constant downward acceleration a=g
