2. A 220 g ball travelling East with a velocity of 4.2 m/s, collides with a 300 g ball at rest. A glancing collision occurs and the ball that was at rest is now moving with a velocity of 2.1 m/s [E 40ᵒ S].
Determine the velocity (and direction) of the other ball. [6]

For question 2 above determine whether kinetic energy was conserved and explain by citing the type of

collision. [4]

Aweather balloon has a volume of 52.5 liters at a temperature of 252 k. the balloon is released and rises to an altitude where the temperature is 295 k. how does this temperature change affect the gas particle motion?

The law of entropy can also be called the law of increasing disorder, but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. prepare for a class debate on the validity of the following arguments: a. living things are not subject to the laws of thermodynamics. b. the increase in the universe's entropy due to life processes is greater than the decrease in entropy within a living organism.
