An 82 g arrow is fired from a bow whose string exerts an average force of 95 n on the arrow over a distance of 77 cm. what is th
Zigmanuir [339]
You need to find speed, v.
And you (should) recognize the famous F=ma.

We've got data for F and m, so we can find a first!
a =  \frac{f}{m}
a = 95N / 0.082 kg


Now from a we nees to find v. But how is v and a related?
a =  v \times \frac{dv}{dx}
where dv is the change in speed (some unknown v minus zero since arrow is initially at rest). dx is the distance where the arrow experiences a force (77 cm!).

Now you know values for a, dv, and dx... you can plug those in and find v!
