Two springs are joined and connected to a block of mass III as shown in Fig. 17-31. The surfaces are frictionless. If the springs separately have force constants k1 and k2, show that the frequency of oscillation of the block iswhere f1 and f2 are the frequencies at which the block would oscillate if connected only to spring 1 or spring 2. (The electrical analog of this system is a parallel combination of two capacitors.)
