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 the speed of the arrow as it leaves the bow?

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 = 95N / 0.082 kg

Now from a we nees to find v. But how is v and a related?

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!

Ihope you get it right bro

B) raising the temperature and reducing the volume of the gas.|-/
