This problem really shouldn't be this difficult but for some reason I can't seem to find the answer.(adsbygoogle = window.adsbygoogle || []).push({});

An arrow, starting from rest, leaves the bow with a speed of 26.0 m/s. If the average force exerted on the arrow by the bow were doubled, all else remaining the same, with what speed would the arrow leave the bow?

net force= mass x acceleration

Acceleration is unknown in this question. Velocity (I'm assuming it's the final V?) is known (26.0 m/s). Initial velocity is 0. I know that when force doubles, acceleration doubles. That's about as far as I could get.
