1. The windows in an office building are 4.26 m by 5.26 m. On astormy day, air is blowing at 53.0 m/s past a window on the 53rdfloor. Find the magnitude and direction of the net force on thewindow. The density of air at that height is 1.23 kg/m3.
2.A sniper fires a rifle bullet into a gasoline tank, making a hole53.0 m below the surface of the gasoline. The tank was sealed andthe absolute pressure at the surface of the gasoline is 3.1 atm.The stored gasoline has a density of 660.0 kg/m3. At what speed vdoes the gasoline begin to shoot out of the hole? Assume thepressure outside the tank is 1 atm
3.A square plate with edge length 9.10 cm and mass 488 g is hingedalong one side. If air is blown over the upper surface only, whatspeed must the air have to hold the plate horizontally. Assume theair density to be 1.21 kg/m3
