A ball moving horizontally at a speed of 0.5 m / s hit the same resting ball. As a result of the collision, the first ball stopped. At what speed did the second ball begin to move after the collision?
if the masses of the balls are the same, then the speed changes will be the same, if the first has the speed of 0. then the second changes from 0 to 0.5 m / s and becomes 0.5 m / s.
