Question

A uniform disc of mass m and radius R rotates about a fixed vertical axis passing through its centre with angular velocity omega. A particle of same angular velocity mass m and moving horizontally with velocity 2omegaR towards centre of the disc collides and sticks to its rim. The angular velocity of the disc after the particle sticks to it is

Answer 1

Answer:

Since the particle of mass hits the rim radially and sticks to it, there is no torque acting on the particle about the center O.Hence, angular momentum
