Question
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.

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.
