Asteel ball bearing of mass 0.06 kg at a height of 1.5m above a steel tables is released from rest and it is found to rebound to a height of 1.3m calculate the gravitational potential energy lost during the fall and the kinetic energy of the ball bearing jusr before impact and the speed of the ball bearing just before impact and the gravitational potential energy gained by the ball bearing when it rebounds to a height of 1.3m. assume that the gravitational field strength is g=10n/kg

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
