R radius of circular disk with mass m with initial velocity v and an angular velocity w comes into contact with the ground as shown in the figure. Friction is not negligible, so both the velocity and angular velocity of the disk changes. What is the critical velocity (VC) when the comes to instantaneous rest (in terms of angular velocity wc and R)
