A light spring with spring constant 1200 N/m is hung from an elevated support. From its lower end a second light spring is hung, which has spring constant 1 800 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.
