a. What are all the variables that could have an effect on the path of a bullet?

b. How do these variables affect the bullet's path?

c. Why is it more important for snipers to pay attention to these variables than close range gunman?

d. From one mile away (5280 feet), how much higher does a sniper need to aim just to account for gravity (32.2 feet per second squared) if his bullet can travel 3500 feet per second straight horizontally?

**Solution:** Bullet will get there in 5280 ft/(3500 ft/s)

= 1.5 seconds

-> distance bullet will fall .5*32.2 ft/s^2 *(1.5s)^2
= 36.2 feet above the target
