    1. The problem statement, all variables and given/known data

    An archer shoots an arrow horizontally at a target 16m away. The arrow is aimed directly at the center of the target, but it hits 56cm lower. What was the initial speed of the arrow?

    2. Relevant equations

    im not sure of an equation because it does not have t.

    3. The attempt at a solution

    I tried V^2=Vo^2+2adeltax

    Maybe if you figured out how long it takes something to fall 56 cm you'd be good to go?
