A mass of 1 kg is hung vertically from a spring stretching the spring .20 m. It is then pulled .10 m below its equilibrium position and released from rest. Find
(a) the angular frequency of oscillation
(b) the spring constant of the spring
(c) the amplitude of oscillation
(d) the kinetic energy of mass when passing through equilibrium
(e) the potential energy of the spring when the mass passes through equilibrium
(f) the time to first reach equilibrium
(g) the time to make one complete cycle.
