Revolt · Accepted Answer

✔ –2; Before the collision, snowball A was 7 kg and had initial momentum of –14 kg · m/s; therefore, its velocity must have been m/s.: –2; Snowball B had initial momentum of 15 kg ∙ m/s, and a velocity of 5 m/s; therefore, its mass must have been kg.: 3; Recognizing that momentum is conserved in inelastic collisions, the total momentum of the combined snowballs after the collision must be kg · m/s.: 1
