28. Question Column 3-400 If I am in a car that stops suddenly, what will happen to me and why?

29. Answer Column 3-400 I will continue to move forward until the seat belt stops me, because anything in motion will stay in motion (me) until a force acts on it (seatbelt).

30. Question Column 3-500 TrialWeightNewtonsSpeed 11000 g1035 m/sec 21000 g20 In the experiment above, what is the speed of the second trial? Why do you think so?

31. Answer Column 3-500 The speed should be double or 70 m/sec because if you double the force, you double the speed.
