Abasketball has a mass of 1 kg and is traveling 12 m / s . how fast would a 6 kg bowling ball have to travel to have the same momentum ?
a. 1 m/s
b. 2 m/s
c. 3 m/s
d. 4 m/s

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

What are two different ways you could find the value of a? explain these methods.

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
