A pleasure filled Excursion into the realm of Physics: 1. Before applying the Super Teflon Anti-friction spray Clark Griswold reviews the trial run stats. His 85.0 kg mass took 5.00 sec to stop with an applied force of 15.0 N. The titanium disc sled had a mass of 5.20 kg. What is Clark's velocity before the stopping force is applied?

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
