At what angle should the gun be aimed to hit the target?

[ross the hoss]

A hunter aims directly at a target (on the same level) 140 m away.

a. if the bullet leaves the gun at a speed of 240m/s, by how much will it miss the target?

b. At what angle should the gun be aimed to hit the target?

could someone please help us figure out which equations to use to solve a and b? that would be wonderful because we have tried all we know and can't find the correct answer.

Try to picture what is going on. The bullet has no vertical velocity so you can just imagine that it's dropped from a certain height. If you knew how long the bullet was in the air for, you could find out how far it fell in that time.
