A solid cylinder of mass 2 kg and radius...

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?

A

0.12 J-s

B

12 J-s

C

1.2 J-s

D

1.12 J-s

Text Solution

Verified by Experts

The correct Answer is:
A
Angular momentum of the cylinder before collision `L= I omega = (1)/(2) MR^(2) omega= (1)/(2) (2) (0.2)^(2) xx 3 = 0.12 J-s`
