Current Topic:
Calculating trajectory of ball rolling down slope and off launch ramp
Bear with me here but I'm trying to digest your last post.  

The ball is rolling down the ramp under the influence of gravity.  This means the ball accelerates linearly down the ramp at gm/s^2.  If the ball doesn't slip, the angular acceleration will be g/circumference/2*pi rad/s^2.  From here I can find the angular velocity knowing the lengths of the ramp and then find the KEr.  

Am I along the right lines here?

I'm ignoring friction totally as I don't know the material of the ramp so have no idea on CoF.
