An ore car of mass 4000 kg starts from rest and rolls downhill on tracks from a mine. A spring with k = 400,000 N/m is located at the end of the tracks. At the spring's maximum compression, the car is at an elevation 10 m lower than its elevation at the starting point. How much is the spring compressed in stopping the ore car? Ignore friction.
