34. To cover their tracks, some criminals decide to roll their getaway car down a hill and off a cliff, where it crashes into a river 40.5 m below. The car is moving horizontally as it leaves
the cliff and the bad guys hear the sound of its splash 3.008 s after the car becomes airborne.
Assuming the speed of sound in air is 342 m/s, determine the speed of the car as it leaves
the cliff.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
