A putty ball of mass m, moving with speed V, strikes the rod at angle θ from the normal and sticks to the rod after the collision. What is the angular speed ωf of the system immediately after the collision, in terms of system parameters and I?Question

A rod of mass *M* and length *L* can rotate about a hinge at its left end and is initially at rest. A putty ball of mass *m*, moving with speed *V*, strikes the rod at angle *θ* from the normal and sticks to the rod after the collision. What is the angular speed *ω*_{f} of the system immediately after the collision, in terms of system parameters and *I*?
