A 1.5 kg block is connected by a rope across a 50-cm-diameter, 2.0 kg , pulley that spins on a frictionless axle, as shown in (Figure 1). A constant 10 N tension is applied to the other end of the rope. Starting from rest, how long does it take the block to move 30 cm ?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a pistonācylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressureāvolume relationship between the same end states. reference
