# Trypanomic problem!

In the figure , three $$10000$$ kg ore cars are held at rest on a mine railway using a cable that is parallel to the rails, which are inclined at angle $$\theta = 30°$$ . The cable stretches $$15$$ cm just before the coupling between the longer two cars breaks, detaching the lowest car . Assuming that the cable obeys Hooke’s law, find the amplitude (in meters) of the resulting oscillations of the remaining two cars.
