Homework Help: college physics

Posted by patti on Friday, March 15, 2013 at 7:12pm.

if a 12kg ball rolls down a ramp at 3 m/s and crashes into a pillow and it takes 0.65 s to stop the ball what is the momentum of the ball and the force exerted by the pillow? I would like to know the formula on how to figure this out.
