Question

A mass is attached to a vertical spring, which then goes into oscillation. At the high point of the oscillation, the spring is in the original unstretched equilibrium position it had before the mass was attached; the low point is 8.6cm below this.

What is the period of oscillation?
A mass of 0.5kg is attached to one end of a helical spring and produces an extension of 2.5cm. The mass is now set into verticals oscillation of amplitude 10mm.determine
1.the period of oscillation
2. the maximum kinetic energy of the mass (g=10m/s-2 )
