the following is a physics question. Thank you in advance!

A cue ball initially moving at 3.5 m/s strikes 1. 2.75681 a stationary eight ball of the same size and mass. After the collision, the cue ball's final O 2. 3.90512 speed is 1.5 m/s at an angle of 0 with respect to its original line of motion. 3. 2.33238 Before 4. 3.32415 1.5 m/s 3.5 m/s 5. 3.52136 O 6. 1.78885 After 7. 3.74166 Find the eight ball's speed after the col- lision. Assume an elastic collision (ignoring 8. 1.95959 friction and rotational motion). Answer in units of m/s. Answer in units of 9. 2.09914 m/s. 10. 3.16228
