Projectile problem -- How much to increase Vi to reach a farther target?

[QUOTE="SteamKing, post: 4989824, member: 301881"] Such ranges and launch angles usually suggest that the rocket gains a relatively large altitude before hitting its target. Your range formula assumes that g is constant, which is OK for problems where the projectile remains close to the surface of the earth. For projectiles which travel high in the atmosphere, I'm sure this formula must be modified. The variation of g with altitude is discussed in this article: [URL]http://en.wikipedia.org/wiki/Gravity_of_Earth[/URL] This might be the source of the discrepancy of your calculation with the answer key.
