Question
An aircraft flying at 200 m / sec fires sideways-pointing machine guns. The muzzle velocity of the shells from the guns is 800 m / sec. What is the velocity of the shells, in m / sec, relative to the Earth? Select one: a. sqrt(2002 + 8002) b. sqrt(200) + sqrt(800) c. 200 + sqrt(800) d. sqrt(200) + 800 An aircraft flying at 200 m / sec fires sideways-pointing machine guns.
