1. With Friction and Air Drag turned off, describe the effect
that an applied force has upon the velocity? Also, draw the
force diagram at the right. Label the forces using Fapp for
Applied force, Fnorm for Normal force from the ground, and
Fgray for the Weight of the sled.

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
