11.8. A merry-go-round is revolving with frequency w. A boy standing at a distance d from the center O is holding a small mass m tied to a string of length L. The mass oscillates wit: simple harmonic motion with a small amplitude. Calculate the period of oscillations. 11.9. A rod is fixed on a turntable in a radial direction starting at the center 0. A bug starts crawling from O toward A radially outward. The bug can hold oato the rod with a maximum force equal'to its weight on Earth. If the turntable is totating with an angular frequency w, how far can the bug craw! before it loses its grip?
