I am trying to do a pratice test and I am stuck on this problem.(adsbygoogle = window.adsbygoogle || []).push({});

a disk of radius r=0.5m,mass m=0.25kg has an initial angular speed of w=23rad/s.assume a torque of 0.33Nm is applied against the rotation for an angular distance of 20 rad. what is the final angular speed?

thanks for any help.:surprised :surprised
