A gun fires a projectile toward a target that is 4.54 km distant at the same elevation as the gun. The gunnery officer notes that the projectile hit the target 27.5 s after firing. a)Find the angle of elevation of the gun barrel. b)Find the initial speed of the projectile. So x=4.54 km t = 27.5 s I am really confused on how to solve this problem. It seems there isn't enough information to solve the problem or either I am missing something simple. Any help to get part A started would be great.
