A 120g cue ball moving at 0.35m/s strikes a stationary target ball with the same mass. After the collision, the cue ball moves at 0.18m/s at 60 degrees from its original line of motion.

PART A: Find the system's center-of-mass velocity before the collision.

PART B: Find the system's center-of-mass velocity after the collision.
