A pair of identical balls are connected by a massless rod, and thrown straight up into the air, such that the center of mass of the pair reaches a maximum height of 13.2 m above the point of release. Exactly 1.0 s after reaching this height, the velocity of one ball is measured to be 3.2 m/s upward. What is the velocity of the other ball at this time

With i really need the correct answer!

State the following: boyle's law and charle's law

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
