Heres the question:
Assume an elastic collision (ignoring friction and rotational motion).
A cue ball initially moving at 3 m/s strikes a stationary eight ball of the same size and mass. After the collision the cue ball's final speed is 1.4 m/s.
Find the eight ball's angle with respec to the original line of motion of the cue ball.
-------------------
I can't really post a diagram for you guys to see, but the cue ball is a little above the eight ball (from a birds eye view, left to right). So when the collide the eight ball is moving at a downwardish angle (this is the angle i am supposed to find) and the cue ball is moving upwards.
This question kind of threw me off bc in class we are studying work and kinetic energy etc. All of our homework problems have been about that so far. I can't seem to find a way to incorporate those concepts into this problem.
Should it just be done as a conservation of momentum problem?
Can anyone point me in the right direction?
