A solid cylinder of mass 2 kg and radius 0.2m is rotating about its own axis without friction with angular velocity 3 rads/s. A particle of mass 0.5 kg and moving with a velocity 5 m/s strikes the cylinder and sticks to it as shown in figure. The angular momentum of the cylinder before collision will be?

Options

A. 0.12J-s
B. 12J-s
C. 1.2J-s
D. 1.12J-s

Explanation

(1)Angular momentum of the cylinder before collision `L=Iomega=1/2MR^2omega=1/2(2)(0.2)^2xx3`.
