    The angular velocity is defined as "the angle changing over time."

    From the given of the problem:

    m = 100g

    rate of revolution = 50 rev / min

    Therefore, using the formula:

    angular velocity = rate of revolution x 2*pi / revolution

    Substituting:

    angular velocity = (50 revs / min) x (2*pi radians / rev) = 100*pi radians / min

    As you can see, mass is not a part of the equation for solving the angular velocity therefore the amount of mass does not affect its value.
