Car 1 has a mass of 1.50 × 10° kg and is moving at a constant speed of 4.00 m/s. It strikes Car 2, which is at rest and has a mass of 1.20 x 10° kg. The cars lock together and continue to roll forward. They then collide and lock together with Car 3, which is at rest and has a mass of 1.80 x 10° kg. Before First Collision Car 1 Car 2 Car 3 v, = 4.00 m/s v, = 0 m/s V = 0 m/s
