Golfer Arnold Hacker requires three putts from position A to put his ball in the hole. His first putt, from A to B, travels 8.0 m south. His second putt, from B to C, travels 1.2 m southwest. His third putt, from C to the hole at D, travels 0.50 m northwest. What would be the magnitude and direction of the single putt that would have put the ball into the hole, from A to D?​

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
