Quote:If ball A is moving at 2kph in direction 156 degrees and collides with ball B which is moving at 6kph in direction 257 degrees what is the final speed and direction of the balls?This is a vector problem. The velocities are magnitudes. You can use linear algebra to solve it. You still shouldn't hustle people in billiards. It always leads to trouble.
