The plane of the figure represents a horizontal plane. A thin rigid rod at rest is pivoted without friction about a fixed vertical axis passing through O. Its mass moment of inertia is equal to 0.1 kg∙cm2 about O. A point mass of 0.001 kg hits it normally at 200 cm/s at the location shown, and sticks to it. Immediately after the impact, the angular velocity of the rod is ___________ rad/s (in integer)..
    Correct answer is '10'. Can you explain this answer?

    Given data Mass of particle (m) = 0.001 kg
    Velocity of particle (v) = 200 cm/s
    Moment of inertia about point O (I0)  = 0.1 kg - cm2

    Let us angular velocity of rod = ω'rad/s
    We know, Momentum conservation principle

    Hence, the angular velocity of rod ω'r = 10 rad/s
    Hence, the correct answer is 10.
