 Part 1: Momentum principle from week 5.
+Two rocks are floating off in space. You've observed that the first rock has a mass of 3000 kg and an initial velocity of 20 m/s. The second rock has a mass of 1000 kg and no initial velocity. The two rocks collide; rock one hits rock two, leaving rock one with a velocity of 10 m/s.
+a) What is rock two's final velocity?

 Part 2: Momentum principle from week 5.
+In a different collision, the two rocks have the same initial parameters, but when they collide, they attach and move off together in the same direction.
+b) What is the final velocity of the attached rocks?
