SUMMARY
In the discussion, two freight cars, each with a mass of 2.5 x 105 kg, collide in a completely inelastic collision. One car is moving at 3.4 m/s while the other is at rest. Using the conservation of momentum formula, m1v1 + m2v2 = (m1 + m2)v', the final speed (v') of the combined mass after the collision is calculated to be 1.7 m/s.
