Coefficient of Restitution? PLEASE HELP!
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.
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
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?
