The spring mass system is shown in the figure. The spring stretches 2 cm from its free length when a force of 10 N is applied. This spring is stretched 10 cm from its free length, a body of mass m = 2kg attached to it and released from rest at time t = 0. Find
(a) the force constant of the spring.
(b) the time period and frequency of vibration
(c) the amplitude of vibration.
(d) the initial velocity and acceleration
