This question is driving me insane...
An arrow, starting from rest, leaves the bow with a speed of 25.0 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?
Of course, instinct says 50 m/s, but it's never that simple! I have no idea where to start with this, it seems like too much information is missing.
A general prod in the right direction would be appreciated- please don't tell me something like "use F=ma", because I *know* that. What I *don't* know is how to get the force, or the mass, or the acceleration.
Thanks =)
