Question

Co (3.2) 2.2 mo tan-i(ca)/(k-ma)-)), show that (3.2) may be equivalently (d) Using ω,- k/ m and θ expressed in the form (3.3) Hint: cos(α-β)-cosacosß+ sinasinß (e) Observe that the amplitude of the oscillation of y, in (3.3) is A(o)- 2 12 and that ao, m, and c are fixed constants determined by the given spring-mass system. We now examine how the size of these oscillations depends on a. First, compute Then, set đΔ/da) 0 to show that the maximum amplitude occurs when (3.4)
