A2.1-kg brick is placed gently upon a 2.9-kg cart originally moving with a speed of 26 cm/s. determine the post-collision speed of the combination of brick and cart.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder 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 pressure–volume relationship between the same end states. reference
