2. A “scientist” is blowing up a dead whale
A “scientist” is blowing up a dead whale. The back half of the whale has a mass of 150 kg and travels 5 m/s to the WEST. If the front of the whale has a mass of 60 kg, how fast is it traveling and in what direction? What type of collision is this?

4. Car A hits Car B in an accident
Car A hits Car B in an accident. What mass and velocity of Car A would produce the largest collision?

6. A runner (56 kg) traveling 4 m/s comes to an abrupt stop
A runner (56 kg) traveling 4 m/s comes to an abrupt stop. Calculate the impulse. Calculate the change in momentum.

8. Why are crumple zones a positive for newer automobiles
Why are crumple zones a positive for newer automobiles? (Use Physics Jargon)

10. Two objects (a ball and sticky mat) collide and stick together
Two objects (a ball and sticky mat) collide and stick together. What type of collision is this? What is true of the velocity after the collision?

11. In the previous question, the ball (7 kg) is travelling 20 m/s
In the previous question, the ball (7 kg) is travelling 20 m/s. If the sticky mat has a mass of 10 kg, what is the new velocity of the ball/ mat combo?

13. A soccer player kicks a ball with a mass of 0. 24 kg
A soccer player kicks a ball with a mass of 0.24 kg. If the force of the kick averages 1710 N, and the force acts on the ball for seconds, calculate the speed of the ball.

15. Your truck (mass = 2700 kg) gets stuck in mud
Your truck (mass = 2700 kg) gets stuck in mud. Calculate the momentum if you are pushing the truck forward 14 m/s into a 6 m/s wind (pushing against you).
