A solid 0.6750 kg 0.6750 kg ball rolls without slipping down a track toward a vertical loop of radius R = 0.6750 m R=0.6750 m . What minimum translational speed v min vmin must the ball have when it is a height H = 1.039 m H=1.039 m above the bottom of the loop in order to complete the loop without falling off the track? Assume that the radius of the ball itself is much smaller than the loop radius R R . Use g = 9.810 m/s 2 g=9.810 m/s2 for the acceleration due to gravity.

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
