• Question 1: Firing a gun into the air. Suppose a bullet is fired straight upwards and that it leaves the barrel of the gun at 200 m/s. Neglecting air resistance, how fast will it be going when it comes down? What will happen to a person who happens to be where the bullet comes down?
  • Question 2: Same question as above, but – one approach to solving problems is to start with an “idealized case”. In the question above we made the approximation that air resistance was negligible, then we say, “What happens if we make the situation less ideal?”
  • Question 8: State Newton’s first law of motion and give an example of what it means.
