A certain uniform spring has a spring constant k. Now the spring is cut in half. What is the relationship between k and the spring constant k' of each resulting spring? Explain your reasoning.
A light spring with spring constant k1 is hung from elevated support. From its lower end, a second light spring is hung, which has spring constant k2. An object of mass m is hung at rest from the lower end of the second spring,
(a) What is the total extension distance of the pair of springs?
(b) What is the effective spring constant k of the two-spring system?
