A billiard ball at rest is struck by an identical ball coming in from the left with a speed of 5.0m/s. After am elastic collision, the striking ball goes off at the angle of 40 degrees counter clockwise with respect to its original direction of motion. The struck ball goes off at an angle of 50 degrees clockwise with respect to this direction. Find the final speeds of the two balls.
