Friction and force

A mass of 0.3kg is suspended from a spring of stiffness 200nm^-1. If the mass is displaced by 10mm from its equilibrium position and released, for the resulting vibration, calculate;

The maximum velocity of the mass during the vibration

The maximum acceleration of the mass during vibration

Additional info; mass of wheel 3kg, outside radius of wheel 300mm, radius of gyration 212mm

Re: Friction and force

Have you tried Hooke's law?

WHAT "wheel"? And what happened to the "friction" in your title?
