A massless spring with spring constant 20 N/m hangs vertically. A body of mass0.15 kg is attached to its free endand then released. Assume that the spring was unstretched beforethe body was released.
(a) Find how far below the initial position the bodydescends.
m
(b) Find the frequency of the resulting motion, assumed to besimple harmonic.
Hz
(c) Find the amplitude of the resulting motion.
