AnswerA tell me what u got sorry if its worng
Explanation:
This is a conservation of momentum question. Initial momentum of the system is the momentum of ball 1 plus the momentum of ball 2. The final momentum of the system should be 0 since the balls stand still after the collision.
mv + mv = 0
mv = -mv
(20)(20) = -(40)Vi
400 = -40Vi
Vi = -10
So ball 2 should travel at 10m/s to the left
