Example 5.1 A ball is kicked off horizontally from the edge of a cliff with velocity of magnitude 9.0 m/s. Find
the ball's position, distance from the edge of the cliff, and velocity after 0.50s.

Apassenger walks toward the rear of a moving train. describe her motion as seen from a reference point on the train. then describe it from a reference point on the ground

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

In a system, when potential energy decreases, then entropy also decreases. true false
