Two people are attached to each other to go tandem sky diving. Person A has a mass of 72.3 kg, Person B has a mass of 75.4 kg, and the parachute has a mass of 6.0 kg. After several seconds of sky diving and accelerating they open the parachute and eventually reach a slow and steady terminal velocity. Determine the force of air resistance on the sky divers after the parachute opens.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
