Discussion :: PKRB: Impulse and Momentum - General Questions (Q.No.4)


The uniform pole has a mass of 15 kg and falls from rest when = 90° until it strikes the edge at A, = 60°. If the pole then begins to pivot about this point after contact, determine the pole's angular velocity just after the impact. Assume that the pole does not slip at B as it falls until it strikes A.

[A]. 3 = 1.146 rad/s
[B]. 3 = 0.537 rad/s
[C]. 3 = 2.15 rad/s
[D]. 3 = 1.528 rad/s

Answer: Option D
