Request Description

1. 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.

2. A pedndulum suspnded 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:

a) upward with constant speed

b)downward with constant speed

c) downward with constant upward acceleration

d) upward with constant upward acceleration

e) upward with constant downward acceleration a=g

f) downward with constnat downward acceleration a=g
