3. A bunny and a tortoise start a race from rest. The bunny accelerates at a rate ab for a time to until it reaches its maximum speed (vb) after traveling a distance db. The tortoise accelerates at a rate one forth as great as the bunny and
takes three times as long to reach its maximum speed of vt after traveling a distance dt.

a) What is the maximum speed of the tortoise? Answer in terms of vb

b)How far did the tortoise travel? Answer in terms of db

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
