21 22 A thin rod of mass m and length L lies on a frictionless horizontal surface and is hinged at one of its ends such that it can rotate freely about a vertical axis passing through the hinge A particle of same mass m hits the rod at the extreme end as shown with velocity vo and does not stick with rod and come to rest immediately such that the rod rotates with a constant angular velocity w after the collision 1 Then angular velocity just after collision is equal to 3v0 L A 2v0 5L A B 2 Magnitude of hinge reaction just after the collision is 7mv 5mv 2L 2L B C C 5vo 7L 9mv 2L D D 5vo 9L 9mv 4L N s m
