Hamden is driving at 25 m/s. He sees cows are slipping across the road. He applies the break to stop his car when cows are 58 m in front of him. If the coefficient of kinetic friction between the car’s locked tires and the road is 0.52, will the car stop before hitting cows? The mass of the car and Hamden together is 1500 kg.

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
