If a bullet that leaves the muzzle of a gun at 260 m/s is to hit a target 102 m away at the level of the muzzle (1.6 m above level ground), the gun must be aimed at a point above the target. (Ignore any effects due to air resistance.)

2. Relevant equations
I just need help with understanding the question. I know that the height for y is 1.6 at the starting point, but how do i know how tall the target is?

3. The attempt at a solution

You are told that the target is at the same level as the gun.

I think your problem isn't advanced, better you've posted it at "introductory physics"!

And where is your attempt (think about that the trajectory of the bullet is a parabola)?

We also have no idea what you're solving for. I highly doubt they would ask you how tall the target is, since that's given in the equation.
