a golfer hits a golf ball giving it an initial velocity 30m/s at an angle 45° from the horizontal. ignoring air resistance on a flat golf course, how far does the ball travel before first contacting the ground?

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
