The figure shown is just before collision, the velocity of centre of uniform disc is \[{{v}_{0}}\]vertically downward & \[{{\omega }_{0}}\]is the angular velocity as shown. If is found that collision is elastic and after collision disc stops rotating then if coefficient of friction is \[\left( \frac{1}{P} \right)\]then the value of P is? If\[{{v}_{0}}={{R}_{\omega 0}}\]. (R is radius of disc)
