In the figure here, a 28 kg child stands on the edge of a stationary merry-go-round of radius 2.5 m. The rotational inertia of the merry-go-round about its rotation axis is 170 kg-m². The child catches a ball of mass 1.4 kg thrown by a friend. Just before the ball is caught, it has a horizontal velocity of magnitude 12 m/s, at angle = 5 with a line tangent to the outer edge of the merry-go-round, as shown. What is the angular speed of the merry-go-round just after the ball is caught? Child Ball
