1.) Ariel dropped a golf ball from her second story window. The ball starts from rest and hits the sidewalk 1.8 s later with a velocity of 18.7 m/s. Find the average
acceleration of the golf ball.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

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
