Chapter 4, Problem 62P
Two springs have the same unstretched length but different spring constants, k1 and k2. (a) If they’re connected side by side and stretched a distance x, as shown in Fig. 4.25a, show that the force exerted by the combination is (k1 + k2)x. (b) If they’re connected end to end (Fig. 4.25b) and the combination is stretched a distance show that they exert a force k1k2x/(k1 + k2).
