Problem 2 An object of mass m sits on top of a horizontal plate. The plate (P) oscillates horizontally (perpendicular to Earth's gravity). The oscillation has amplitude is zo = 0.15 m and period T = 1 s. The friction between the body and the plate is so that the body just stays on the plate without slipping. Find the coefficient of friction between the plate and the body. Note that he maximal friction force between the plate and body is μN where N is the magnitude of the normal force. m 0 x = x cos at

O Macmillan Learning A small bolt with a mass of 27.0 g sits on top of a piston. The piston is undergoing simple harmonic motion in the vertical direction with a frequency of 1.45 Hz. Use g = 9.81 m/s² for the acceleration due to gravity. What is the maximum amplitude Amax with which the piston can oscillate without the bolt losing contact with the piston's surface? Amax = m
