A wheel is rotating in a counterclockwise direction about its center. Then suppose the rotation rate slows to zero and then speeds up to an even greater value in the opposite direction. For an object attached to the rim of the wheel: (the equation for centripetal acceleration aC = vt2/r, where vt = tangential velocity and r is the wheel radius)
What happens to the direction of the centripetal acceleration vector (what’s the overall change in the direction)?

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
