During a snowball fight, two snowballs travelling towards each other collide head-on. The first is moving east at a speed of 15.3 m/s and has a mass of 0.450 kg. The second is moving west at 13.5 m/s. When the snowballs collide, they stick together and travel west at 3.50 meters per second. What is the mass of the second snowball?
A 0.22kg arrow with a velocity of 15.00 m/s to the west strikes and pierces the center of a 3.00 kg target. What is the final velocity of combined mass? Answer in m/s.
