A massless spring hangs from the ceiling with a small object attached to its lower end. The object is initially held at rest in a position yi such that the spring is at its rest length. The object is then released from yi and oscillates up and down, with its lowest position being 14 cm below yi.
(a) What is the frequency of the oscillation?
Hz
(b) What is the speed of the object when it is 12.0 cm below the
initial position?
m/s
(c) An object of mass 275 g is attached to the first object, after
which the system oscillates with half the original frequency. What
is the mass of the first object?
g
(d) How far below yi is the new equilibrium
(rest) position with both objects attached to the spring?
m
