Displacement, Velocity and Acceleration

  1. Sep 18, 2009 #1
    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.
