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

The phase space trajectory of an undamped oscillator is shown below. In the diagram, eachdivision along the position axis corresponds to 0.1 m; along the velocity axis, 0.10 m/s. What is the angular frequency ?Aof the undamped oscillator? Explain how you can tell.
