A20kg boy stands on a small stationary (at rest) merry-go-round near the edge of the merry-go-round. the total moment of inertia of the system of merry-go-round with the boy on it about the center is 120kg m2 . the boy at the edge of the merry-go-round (radius of 2m) jumps off the merry-go-round in a tangential direction with a liner speed of 1.5m/s. what is the angular speed of the merry-go-round after the boy leaves it?
