A merry-go-round is spinning and has a period of 7.25 s. A boy jumps off in a direction parallel to the radius and, by so doing, changes the moment of inertia of the merry-go-round from 575 kg·m2to 545 kg·m2. By conservation of angular momentum, approximately what is the new period of the merry-go-round?
