Consider two massless springs connected in series. Spring 1 has aspring constant k_1, and spring 2 has a springconstant k_2. A constant force ofmagnitude F is being applied to theright. When the two springs are connected in this way, they form asystem equivalent to a single spring of springconstant k.
What is the effectivespring constant k of the two-spring system?
Express the effectivespring constant in terms of k_1 and k_2.
