Amass of 25 k g is suspended from a spring which has a stiffness of 14 kn/m nsion. it vibrates freely with an amplitude of 12 mm. find the periodic time, the velocity and acceleration when displaced 8 mm from the equilibrium position and time interval in passing from this position to the position of maxi- of exte mum displacement.
