Two of the smallest particles known to man, the Kauaion and the Waimeaon have just been discovered! The Kauaion has a mass that is 3 times larger than the Waimeaon. The particles were discovered in a 1-D collision travelling towards each other where the Kauaion had a velocity of 50000m/s  and the Waimeaon had a velocity of 100000m/s . The particles underwent a completely elastic collision. Find the velocity of the Kauaion and the Waimeaon after the collision.

Part A:
After the collision, the Kauaion has a velocity of:
_____ m/s

Part B:
After the collision, the Waimeaon has a velocity of:
_____ m/s
