Answer on Mechanics | Kinematics | Dynamics Question for Eric
I was wondering if i could get help with this problem:
Two billiard balls of equal mass undergo a head-on collision. The speed of ball 1 was initially 6.00 m/s to the right, and that of ball 2 was 8.00 m/s in the opposite direction (to the left). After they bounce off of each other the speed of ball 1 is 8.00 m/s.
What is the speed of ball 2 after the collision?
