How to find the angular velocity for this question?

  1. Apr 26, 2015 #1
    1. The problem statement, all variables and given/known data
    Finding angular velocity after impact

    2. Relevant equations
    Moment of inertia x angular velocity = constant

    3. The attempt at a solution
    Hi, I believe that angular momentum is conserved in this case?
    If thats the case, how do I use the formula to calculate angular velocity if the intial angular velocity is already 0?

    If there is angular momentum after the impact but not before, then AM canot be conserved.

    The bar is fallling at an angle of 60°. After it hits the ground, one end is anchored to the ground and the bar begins to rotate.

    Generally, momentum is not conserved in a collision with the Earth, unless you include the Earth in your system.
