1. The problem statement, all variables and given/known data I will just try to post the whole questions, maybe my idiot eyes missed something... an arrow is accelerated for a displacement of 75cm [fwd] while it is on the bow, if the arrow leaves the bow at a velocity of 75m/s [fwd] what is it's average acceleration while it's on the bow 2. Relevant equations t = displacement/ velocity a = velocity/time 3. The attempt at a solution 75 cm -> .75 0.75 / 75 = 0.01s disp = 75m t = 75/0.75 = 100s velocity = 75m/s a = velocity / time time = displacement + velocity / velocity acceleration = velocity/(disp/velocity) = vecloity / 0.01 = 7500 WTH!?!?
