Thanks Voko, again I appologise for my lack of understanding, but from what you are saying I understand that the fact that the 2 balls striking at a 45 degree angle is not significant?

thanks for the replies. Mfb, would the lighter part A move upward at a 90 degree angle as depicted?

Would the 2 items displayed in the image below act as I expect in a zero G environment? Assuming that item A had a mass of 100kg and was stationary, Items B have a mass of 1kg and travel at 10m/s. what formula would I need to use to calculate the velocities and vectors of the items after...

Just for clarity, assume the ball has a hole in the center and has the freedom to move up or down the arm as the speed of the rotation increases/decreases.

Hi, I was unsure how to describe what I wanted using words alone so I created a GIF to help. Or view here - http://makeagif.com/i/k7rF6T I am pretty unschooled in the world of physics so please forgive my lack of understanding. Firstly, the force that would cause the ball to move...
