10. A 63 kg astronaut is in space and throws a 10 kg oxygen tank towards Earth with a speed of 12.0 m/s. Assuming the astronaut starts from rest, find the final velocity of the astronaut after the throw.

13. Collisions

14. Elastic Collision A 16 kg canoe moving to the left at 12 m/s makes an elastic head- on-collision with a 4.0 kg raft moving to the right at 6.0 m/s. After the collision, the raft moves to the left at 22.7 m/s. Disregard any water effects. Find the velocity of the second ball after the collision.

15. Inelastic Collisions A 1500 kg traveling at 15 m/s to the south collides with a 4500 kg truck that is initially at rest. The car and truck stick together and move together after the collisions. What is the final velocity of the two vehicle mass?
