An point-like bear of mass m jumps onto marry- go-round with moment of inertia I and radius R. Bear velocity is vo, direction shown at the figure. R2/ 30 : R/2, Marry-go-round is originally at rest and has no friction in its axle. Assuming bear landed at the Vo marry-go-round at distance R/2 away from the center and managed to stop himself with respect to marry-go-round when he was distance 3R/4 from the center find final angular velocity of the merry- go-round with bear on it.
