Final Energy - Initial Energy = Work done by non conservative forcesbob012345 said:What then did you get for the angular velocity? What method?

=> Elastic potential + rotational kinetic energy of s + translational kinetic energy of s - 0 = 0;

; ##\frac 1 2## ##k x_{max}^2## + ##\frac 1 2## ##I_c ω^2## + ##\frac 1 2## ##m_s v_s^2## = 0, I know everything except ##ω## so I can find it.
