A5.0 n block rests on an incline 3 m above the bottom of the incline, as shown. the block is then hit by a hammer so that it has a speed of 1.0 m/s down the incline after being hit. if the incline is 5 m long, and the coefficient of kinetic friction between the block and the incline is μk = 0.75, what is the block's speed when it reaches the bottom of the incline

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
