Read the scenario and choose the correct answers.
Imagine you have just witnessed a small avalanche on a mountain while skiing, and two slushy snowballs just
crashed together in a perfectly inelastic collision. They are moving as one larger snowball, as a combined mass.
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.
Snowball B had initial momentum of 15 kg. m/s, and a velocity of 5 m/s; therefore, its mass must have been kg.
Recognizing that momentum is conserved in inelastic collisions, the total momentum of the combined snowballs after
the collision must be kg. m/s.
