A merry-go-round is spinning at 3.00 revolutions per minute. A crate is placed on it at a distance 2.00 m from the axis of rotation. If the coefficient of static friction between the crate and the surface of the merry-go-round is 0.30, will the crate stay on the merry-go-round, or will it slip and fall over the side?

Answer #1

If friction is enough to provide the necessary centripetal acceleration at this speed then the block will not slide.
