===
1. A 1200 kg car traveling east at a speed of 16 m/s has a head-on collision with a 3000
kg traveling west at 10 m/s. If the vehicles are locked together after the collision,
what is their final velocity v.
2. A 6000 kg final stage of spaceship ejects the 10000 kg second stage. Before ejection,
the two stages travel with a velocity of 200 m/s. If after ejection the second stage
travels at 70 m/s opposite the direction of its initial motion, what is the velocity of
the final stage?
