Physics - Rotation Question with Solution | TestHub

Consider a uniform rod of mass$M=4\mathrm{m}$and length$l$pivoted about its centre. A mass$m$moving with velocity$v$making angle$\theta =\frac{\pi }{4}$to the rod’s long axis collides with one end of the rod and sticks to it. The angular speed of the rod-mass system just after the collision is:
