This is probably simple, so please excuse my ignorance, but it's bugging me. I place the 8 ball in the center of a pool table. Then the 7 ball is place in the front of the table, say, 1 foot from the 8 ball for a direct line shot. I also place the 6 ball on the side, again 1 foot away for a direct side shot on the 8 ball. Two players hit the 6 and 7 ball towards the 8 at exactly the same time and with exactly the same speed and force. Lets say, 10 mph with 1 lb of force. Those two balls impact the 8 ball, and the 8 ball flys-off at a 45 degree angle(I think). Fine. But at what speed and force does the 8 ball travel? And what happens to the 6 and 7 ball after this impact? Thank you for your time.
