A runaway railroad car, with mass 4.50 × 105 kg, coasts across a level track at 3.80 m/s when it collides with a spring-loaded bumper at the end of the track. If the spring constant of the bumper is 3.80 × 106 N/m, what is the maximum compression of the spring during the collision? (Assume the collision is elastic.)
