Hitting a target

  1. Aug 5, 2005 #1
    I need to make sure I am using the correct formulas (dvertical = 1/2at^2 solving for t^2 and dhorizontal = Vot) for the following problem:
    arrow shot horizontally - speed of 100m/s - at bullseye 25 m away. How long til it reaches target and where will it hit target.
    Thanks! :confused:

    Yes, if the arrow is shot horizontally, those are the correct equations. Set dhorizontal= 25 m, a= -9.81 m/s2, and Vo= 100 m/s. Solve the dhorizontal equation for t (how long till it reaches the target) and then use that value to solve for dvertical (where will it hit the target).
