A villain with mass 70.0 kg runs at a velocity of 10.0 m/s into Chuck Norris’ fist moving at a speed of 0.100 m/s. The villain is knocked back at a velocity of 9.44 m/s and angle 20.0° from the horizontal, and Chuck Norris’ fist moves at a velocity of 0.0500 m/s and 10.0° from the horizontal. a. What is the mass of Chuck Norris’ fist in kg? b. How much kinetic energy is lost in the collision?

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.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
