A purple ball that has a mass of 4.2 kg and an orange ball with a mass of 4.7 kg collide in an elastic collision. The purple ball is initially moving to the left
with a velocity of 15 m/s. The orange ball is moving to the right with a velocity of 12 m/s. If the final velocity of the orange ball is 11.3 m/s, what is the final
velocity of the purple ball?

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
