A merry go round of mass 20kg is freely rotating with an angular velocity of w= 3 rad/s. Someone drops a sack of coal of mass 20 kg on the edge of it. What does the angular velocity change to? ___rad/s. Remember that the rotational inertia of a disk (which is what we take the merry-go-round to be), is 0.5 mR²
