Answer:

Explanation:
Given that,
Mass of ball 1, 
Initial speed of ball 1, 
Mass of ball 2, 
Initial speed of ball 2,
(at rest)
After the collision,
Final speed of ball 2, 
Let
is the final speed of ball 1.
Initial momentum of the system is :



Final momentum of the system is :



According the law of conservation of linear momentum :
initial momentum = final momentum


So, the final velocity of ball 1 is (-2.616)m/s.
