An ore car of mass 43000 kg starts from rest and rolls downhill on tracks from a mine. At the end of the tracks, 19 m lower vertically, is a horizontally situated spring with constant 5.6 x 10° N/m. The acceleration of gravity is 9.8 m/s. Ignore frietion. How much is the spring compressed in stop- ping the ore car? Answer in units of m.
