The 10 g head of a bobble-head doll oscillates in SHM at a frequency fo 4.0 Hz.
(a) What is the spring constant of the spring on which the head is mounted?
(b) Suppose the head is pushed 1.4 cm against the spring, then released. What is the head's maximum speed as it oscillates?
(c) The amplitude of the head's oscillation decreases to 0.5 cm in 3.0 s. What is the head's damping constant?
