At the beginning of the compression process of an air-standard Diesel cycle, p1=95kPaandT1=300K. The maximum temperature is 1800 K and the mass of air is 12 g. Forcompression ratios of 15, 18, and 21, determine the network developed, in kJ, the thermalefficiency, and the mean effective pressure, in kPa.

Acar traveling at a constant speed of 22.0 m/s passes a trooper hidden behind a billboard. one second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.50 m/s2. how long does it take the trooper to overtake the speeding car? solve this problem by a graphical method. on the same graph, plot position versus time for the car and the trooper.
