First off i need to make the diclaimer that this is not for any homework or any assignment of any type... i just need to know the answer, and I am not a psyics guy... so please help me out here A ball weighing .5 lbs travels a vertical distance 3 feet downward before changing direction to travel on a horizontal path. Shortly thereafter, it strikes another ball (of same weight) which then travels some distance before striking another identical ball. What are the velocities of the three balls after the second collision? Is there a third collision? You may neglect friction and consider the balls as particles. The coefficient of restitution between all three balls is .85.
