Hi, I was wondering if anyone can help with a problem that has me stumped.(adsbygoogle = window.adsbygoogle || []).push({});

I know the starting position & the landing position of a projectile. (on a level surface)

I also know the initial angle the projectile will be fired at.

I need to find the initial launching velocity of the projectile.

And then how would this be adjusted to take air resistance into account?

Thanks for any help.
