1. The problem statement, all variables and given/known data A 0.065 kg arrow is fired horizontally. The bowstring exerts an average force of 70 N on the arrow over a distance of 0.90 m. With what speed does the arrow leave the bow? 2. Relevant equations W=Fd W=KE final - KE initial KE= 1/2mv^2 3. The attempt at a solution First I used the force given and the distance given and found the work to be 63J. From there I set that equal to the change in kinetic energy. I believe the final kinetic energy is 0, but if that is the case I am obtaining the wrong answer. The final answer is supposed to be 44 m/s.
