based on the myth busters video regarding bullet fired vs bullet dropped

1. If a bullet was fired horizontally but with a larger initial velocity, what effect would this have on the comparison of times between dropped and fired bullet.

2. What would happen to the time comparison of the bullet was fired at an angle above the horizontal?

3. If the apparatus that is used to hold the gun and the apparatus used to drop the bullet we're both moved up by 10cm, what effect would that have on the time comparison?

4. If the gun mount only was moved up 5 cm but was still horizontal, what effect would that have on the time comparison?

5. How would the time comparison change if you dropped a 1-kilogram steel sphere from the same location at the same time the bullet was fired?
