Learning Goal:
To use the conservation of linear momentum to
determine the final state of a group of three objects
that collide and couple together.
The three model train cars shown in (Figure 1) are
moving so that they will all eventually and
couple together. If the initial velocities of the cars are
V₁ = 3,8 m/s, H = 2 m/s, and c = 2.1 m/s in
the directions shown, and the masses are = 2 kg
-m=1.3 kg, and mc 3.6 kg, what is the final
velocity of the cars?
What is the initial momentum of car A? Assume that to the right is positive.
Express your answer to three significant figures with appropriate units.
