2. Calculate the KE for each car in the picture. Each car has a mass of 750 Kg. The 50 mph car, red, has a velocity of 22.35 m/sec. The 100 mph car, yellow, has a velocity of 44.70 m/sec. KE = 0.5m*V? Remember: m means mass, V means velocity. Show your calculations: Use units with numbers!

An air standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes. 1-2 isentropic compression 100 kpa and 22°c to 600 kpa 2-3 v=constant heat addition to 1500 k 3-4 isentropic expansion to 100 kpa 4-1 p=constant heat rejection to initial state (a) show the cycle on p-v and t-s s (b) calculate the net work output per unit mass (409 kj/kg) (c) determine the thermal efficiency (47.9%)
