A disc of moment of inertia 23.4 kg m2 is made to rotate about an axis through its centre by a torque of T . The disc starts from rest, and after {t} s has kinetic energy 632.2 J. Calculate the angular velocity (in rad s-1) after {b} s.
if i work out the angular velocity from the KE=0.5*I*w^2 this equation how do i use it work out the angular momentum from t to b.
