Two kilograms of air within a piston-cylinder assembly execute a carnot power cycle with maximum and minimum temperatures of 750 k and 300 k respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion, the pressure is 600 kpa and the volume is 0.4 m3.
assuming the ideal gas model for the air determine:
(a) the thermal efficiency.
(b) the pressure and the volume at the beginning of the isothermal expansion, in kpa and m3 respectively.
(c) the work and heat transfer for each of the four processes in kj.
(d) sketch the cycle on a p-v coordinates.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
