A uniform rod of length L and mass M is ...

A uniform rod of length `L` and mass `M` is lying on a frictionless horizontal plane and is pivoted at one of its ends as shown in Fig. There is no friction at the pivot. An inelastic ball of mass `m` is fixed with the rod at a distance `L//3` from `O`. A horizontal impulse `J` is given to the rod at a distance `2L//3` from `O` in a direction perpendicular to the rod. Assume that the ball remains in contact with the rod after the collision and impulse `J` acts for a small time interval `/_\t`. Now answer the following questions:

Find the impulse acted on the ball during the time `/_\t`

The correct Answer is:
(a) `omega = ( 6J)/( ( 3M + m ) L) `, (b) ` ( 2mJ )/( ( 3M + m )) `, ( c ) ` ( mJ)/(( 3M+ m ))`
