1. The problem statement, all variables and given/known data

Two balls of equal mass moving with the speed of 3 m/s, collide head on. Find the speed of each after impact if the coefficient of restitution is 1/3.

2. Relevant equations

e=(v2-v1)/(u1-u2)

v2= velocity after impact of object 2

v1= velocity after impact of object 1

u2= velocity before impact of object 2

u1= velocity before impact of object 1

3. The attempt at a solution

I put the numbers into the equation and it yield 0 over something.

The answer is 1 m/s for both ball, but with that into the equation, it would yield 0/0.

My book doesn't say anything on how to do this problem. Maybe it is as simple as multiplying the velocities by 1/3 to get the answer.

Could someone please help me out?
