Task id13364
A billiard ball rolls without sliding along a horizontal plane with speed v and hits the same billiard ball at rest, with the line of centers parallel to the speed of motion. Determine the speeds of both balls after their motion turns into pure rolling. What fraction of the initial kinetic energy will be converted into heat? Assume that when the balls collide, no rotational motion is transmitted. Neglect energy loss due to friction during pure rolling.
