An arrow is fired horizontally at a target that is 40 m away (horizontal d). The arrow drops 0.5 m before striking the target. With what velocity is the arrow fired (what is the horizontal vi)?

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
