Car 1 has a mass of 1.50 x 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 = 4.00 m/s 15=0 m/s =0 m/s Immediately After First Collision Car 1 Car 2 Car 3 V12 Immediately After Second Collision Car 1 Car 2 Car 3 O D) V123 Note: Vector arrows are not drawn to scale. Numerical Response The maximum speed of this three-car system, v23, immediately after the second collision is m/s.
