Question

107. A particle of mass m moving with velocity v hit a
rod of identical mass free to rotate about one end
and stick to it. Find angular velocity of rod just after
collision. (l= length of rod)

(1) v/2l
(2)3v/4l
(3)6v/7l
4)5v/6l​

Answer 1

Answer:

Solution

If we take rod and particle as system we find no external impulse acting on the sytem. Hence, we can use conservation of linear moemntum just before collision just after collision.
