A mass m is moving at speed v perpendicular to a rod of length d and mass M = 6 m which pivots around a frictionless axle running through its centre. If it strikes and sticks to the end of the rod. The moment of inertia of the rod about its centre is Md2/12 . Then the angular speed of the system just after the collision is:
- \(\frac{2 v}{3 d}\)
- \(\frac{2 v}{d}\)
- \(\frac{v}{d}\)
- \(\frac{3 v}{2 d}\)
Answer
(A) 2 v 3 d
