Question

A kid (mass m) runs with a velocity v toward a merry-go-round (moment of inertia I, radius r, initially at rest) and jumps onto its rim. Omega is the magnitude of the final angular velocity of the merry- go-round. Assume no friction. Before After Which statement is true? 6. A The larger I, the larger Omega. B The initial total angular momentum is zero. C The larger m, the smaller Omega. D Due to angular momentum conservation, it is mrv = mr^2Omega. E The magnitude of the initial total angular momentum is mrv. F Due to angular momentum conservation, it is mrv = Iomega.

Explanation / Answer

ans:-E.the magnitude of intial and total angular momentum turn is mrv
