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.

Asmall electric heater, immersed in 80g of water in a calorimeter of 40j/k raises the temperature from 10.5 degree celsius to 25 degree celsius in 12 minutes. using the same apparatus with 50g of oil instead of water, it is found that the temperature of oil rises from 7 degree celsius to 27 degree celsius in 10 minutes. find specific heat capacity of the oil.
