A sinusoidally varying driving force is applied to a damped harmonic oscillator.
(a) What are the units of the damping constant b?
(b) Show that the quantity Vkm has the same units as b.
(c) In terms of Fmax and k. what is the amplitude for "'d = ffm when (i) b = 0.2y'b;; and (ii) b = 0.4y'b;;? Compare your results to Fig. 13.28.
