Car is preserved in the two-coupled cars after collision

Reference no: EM13672601

A railroad freight car, mass 15000kg, is allowed to coast along a level track at a speed of 2.0m/s. It collides and couples with a 50000kg loaded second car, initially at rest and with brakes released. What percentage of the initial kinetic energy of the 15000kg car is preserved in the two-coupled cars after collision?
