A light spring with spring constant 1300 N/m hangs from an elevated support. From its lower end hangs a second light spring, which has spring constant 1700 N/m. An object of mass 1.50 kg is hung at rest from the lower end of the second spring.
(a) Find the total extension distance of the pair of springs.
(b) Find the effective spring constant of the pair of springs as a system. We describe these springs as in series.
