  1. Impulse and Momentum Answers

  2. Answers: Question 1 21,140.5 kgm/s East Question 2 9.26 m/s

  3. Answers: Question 1 10,000 Ns Westward so that means (-10,000 Ns) Question 2 13.99 m/s

  4. Answers: Question 1 5280 kgm/s Question 2 5280 Ns Question 3 88.0 N

  5. Answers: Question 1 The magnitude is the same but the direction is different.

  6. Answers: Question 1 Raindrop

  7. Answers: Question 1 Increasing the time will minimize the force.

  8. Answers: Question 1 1.1 m/s

  9. Answers: Question 1 0.034 m/s

  10. Answers: Question 1 2.8 m/s

  11. Answers: Question 1 2.14 m/s in the opposite direction

  12. Answers: Question 1 Their initial momentum before the impact is equal to their final momentum before they hit the ground.

  13. Answers: Question 1 Yes, the ball’s velocity increases and the racket’s velocity decreases after the collision thereby conserving momentum.

  14. Answers: Question 1 Friction would keep you from moving.

  15. Answers: Question 1 Yes. The bullet with less mass will have a much greater speed than the more massive truck.

  16. Answers: Question 1 Pitcher Question 2 Catcher

  17. Answers: Question 1 Increasing the time of the collision will minimize the force of the impact.

  18. Answers: Question 1 It means that there are no external forces acting on the objects.

  19. Answers: Question 1 It has the same velocity that the cue ball had prior to the impact.

  20. Answers: Question 1 Yes by increasing the time.

  21. Answers: Question 1 If you move your hands in the same direction as the ball you will increase the time of impact thereby minimizing the force.
