Chapter 4, Problem 3Q
When Paris was shelled from 100 km away with the WWI long-range artillery piece “Big Bertha,” the shells were fired at an angle greater than 45° to give them a greater range, possibly even twice as long as at 45°. Does that result mean that the air density at high altitudes increases with altitude or decreases?

A projectile with a muzzle velocity of 400 meter per second is fired from a gun on top of a cliff 400 meters above sea level. If the projectile hits the ocean surface 40 seconds after the being fired, determine the angle of elevation of the gun.
Using a sniper rifle that shoots a bullet projectile at 760 m/s, you will shoot the target at 900 meters with the same elevation. How many millimeters must you raise the muzzle/tip of the gun from the horizon to compensate for the effect of gravity if the gun is 1100 mm long. (Neglect air resistance and Coriolis effect) Moderate: ed out of 900meters 760 m/s.

Your job is to make sure that airplanes are not closer to each other than a minimum safe separation distance of 2.00 km. You observe two small aircraft on your radar screen, out over the ocean surface. The first is at altitude 800 m above the surface, horizontal distance 19.2 km. and 25.0 south of west. The second aircraft is at altitude 1 100 m, horizontal distance 17.6 km, and 20.0 south of west.
