Need Physic help take a look!

This is all you need to figure it out. It’s simple shit, all you need to do is plug the number into the formula.

Ff = mFn
Fn = Fw (Cos theta)
ay = gsin(theta)sin(theta)

I think you need a velocity formula and that’s pretty much it. I cant remember it on top of my head right now. The 2nd one is pretty much plug in the variables into the formula. Dont you have a book? Look it up. I took physics like 6 years ago. That’s all i can remember right now.
