more detail By all else remaining constant, it means that the arrow's displacement (x) remains the same. That seemed to be the general class consensus. The acceleration doubles when the force is doubled, that makes sense, but the next step (actually finding the velocity of such an arrow) is...

Homework Statement An arrow, starting from rest, leaves the bow with a speed of 25.0m/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? Homework Equations F = ma The Attempt at a...

Thank you! That's the same equation I was using to guess and check except I never let the variable be time, always used distance instead. It's kind of funny how your mind can paint itself into a corner. Thanks again, for the help.

6440m - .447m/s(t) / 2403s + t

It would be her velocity going east multiplied by the length of time she walks east so, .447m/s(t)

I can't find any equations that could tell me time given only an initial and final velocity, they all seem to include either the final distance (which I don't know) or the acceleration. I am sorry if I am completely missing the boat here, but I am not at all sure how I would figure out time...

Homework Statement In reaching her destination, a backpacker walks with an average velocity of 1.32m/s due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.68m/s, due west, turns around, and hikes with an average velocity of .447m/s due east. How...
