For Equation 15-45, suppose the amplitude xm is given by Xm = Fm/[m²(w² - w?)2 + b?w&?]1/2 where Fm is the (constant) amplitude of the external oscillating force exerted on the spring by the rigid support in Figure 15-14. Suppose that Fm = 42 N, b = 8.1 kg/s, m = 0.31 kg, and wd = 59 rad/s. At resonance, what are the (a) amplitude and (b) velocity amplitude of the oscillating object? (a) Number i Units (b) Number i Units
