Suppose in the previous poroblem, the child stays at rest on the platform and one of hils firend throws a ball of mas m1 towards thim with a velocity of v from a direction tangential to the platform and the child on the platform catches the ball. Find the angular velocity of the platform after he catches the ball.

Initially the platform with the child is rotating with an angular speed ω 1 ​ . If the child starts walking along its periphery in opposite direction with speed u relative to the platform Suppose in the previous poroblem what will be the new angular speed of the platform.
