6. A 1.50 X 10 4 kg railroad car is moving 7.00 m/s north and collides in an inelastic collision with a car of the same mass<br />
moving 1.50 m/s in the same direction. What is the velocity of the cars after they are joined?<br />
Answer_________________________<br />
7. A 16.0 kg canoe is moving to the left at 12.5 m/s and makes an elastic head-on collision with a 14.0 kg raft moving to<br />
the right at 16.0 m/s. After the collision, the raft moves to the left at 14.4 m/s. What is the velocity of the canoe after<br />
the collision?<br />
Answer_________________________<br />
8. A 25.0 kg bumper car moving to the right at 5.00 m/s overtakes and collides elastically with a 35.0 kg bumper car<br />
moving to the right. After the collision, the 25.0 kg car slows to 1.50 m/s to the right, and the 35.0 kg car moves at<br />
4.50 m/s to the right. What was the velocity of the 35.0 kg car before the collision?<br />
Answer_________________________<br />
9. A 25.0 kg boy is sliding on a frictionless frozen lake at 5.00 m/s to the north when he is struck by a 1.10 kg snowball<br />
moving at 15.0 m/s from the west. If the snowball sticks to him how fast and in what direction does the boy move<br />
after the collision?<br />
Answer_______________________<br />
10. The snowball in #9 was thrown by a 35.0 kg mean-spirited female standing at rest on the same frictionless frozen lake.<br />
How fast and in what direction did this girl move after throwing the snowball?<br />
