The graph shows the displacement from equilibrium of a mass-spring system as a function of time after the vertically hanging system was set in motion at time t = 0. * 0.03 0.02 0.01 -0.01 -0.02 -0.03 Assume that the units of time are seconds, and the units of displacement are meters. The first t-intercept is (0.25, 0) and the first maximum has coordinates (1.25, 0.02). What is the period T of the periodic motion? T=seconds help (numbers) What is the frequency f in Hertz? What is the angular frequency wo in radians / second? f= Hertz help (numbers) wo = radians/second help (numbers) Determine the amplitude C and the phase angle y (in radians), and express the displacement in the form x(t) = C cos(wot - y), with in meters. x(t) meters help (formulas). With what initial displacement y(0) and initial velocity '(0) was the system set into motion? x(0) = x'(0) = meters help (numbers) meters/second help (numbers)
