Aman pushes a lawn mower on a level lawn with a force of 250n. if 40% of this force is directed downward, how much work is done in joules by the man in pushing the mower 6.2 m?

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
