A bullet of mass m moving with velocity v₀(- k ) strikes the bottom of a stationary vertical uniform ring of same mass m and radius R =1 ~m . The ring lies in XY plane with its topmost point hinged on the ceiling. The ring can rotate about X -axis. There is no friction between the hinge and the ring. The bullet gets embedded in the ring immidiately after collision. Find the angular velocity of the system (in radian /

Correct answer

4

Step-by-step solution

mv ₀ 2 R = [ 3 2 mR ^2+ m (2 R )^2 ] ; = 4 v ₀ 11 R =4 rad / s
