(d)
Velocity of the CM of rod =
Applying impulse momentum equation about the CM of rod
About instantaneous axis of rotation the rod is considered to have pure rotation
Let instantaneous axis of rotation be located at a distance from the colliding end
…(i)
Substituting the value of in Eq.(i), we get
