Homework Help: Angular Velocity

  1. Jun 19, 2005 #1
    A 5.4m diameter merry-go-round is rotating freely with an angular velocity of 0.730 rad/s. Its total moment of inertia is 1665kg*m2. Four people standing on the ground, each of mass 60.8kg, suddenly step onto the edge of the merry-go-round. What is the angular velocity of the merry-go-round now? Use units of "rad/s".

    [HINT] :: No external torque use conservation of Angular momentum ::
