Hello, my problem:

A ball (assume its a point) is dropped from height h without initial speed, after some time of falling it will hit an inclined plane (at angle alpha to normal) and bounce off (see the pretty picture, i think it explains a lot).

Question 1: What is the force F?
Question 2: What is the velocity after the bounce?

Started with:
V=(2gh)-1

Ek=(mV2)/2

p=mV => p=m(2gh)-1

F=ma

Q=mg (weight)

My brainstorming yielded this:
Qn=Qcos(alpha)
Fq=Fcos(alpha)

*what is marked as -Fn in the picture* = -(Fn+Qn)

I hope that is it, but I can be forgetful at times. So if you have questions... shoot!
