HHEELLPP?? WILL FAN AND MEDAL!!!
7. An airplane has a gun that fires bullets straight ahead at the speed of 600 miles per hour when tested on the ground while the plane is stationary. The plane takes off and flies east at 600 miles per hour. Explain whether each of the following is possible for the pilot to measure:
a. When fired directly ahead the bullets move eastward at a speed of 1200 miles per hour
b. When fired in the opposite direction (by turning the gun westward, but not the plane), the bullets drop vertically downward
c. If fired vertically downward (by turning the gun downward, but not the plane), the bullets

Answer 5

are you missing a bit of part c?

Answer 6

As far as A and B go, anything is *possible* to measure. Practicality is another thing entirely.

I would say its impractical to measure anything for part A. You'd need either a stationary reference or a reference moving at 1200 mph which is well above the speed of sound. The stationary reference would require the plane to fly by it.. Doable, but it could be a tricky maneuver.

For part B, you simply need to mark your location when you fire bullets backwards and see if they land in that location
