During a storm, the wind exerts a 150-N force on a window that measures 1.00 m by 0.50 m. The outside air pressure is 101 kPa. What pressure, in pascals, does the wind exert on the window?

a. 75 Pa
b. 150 Pa
c. 1.5 x 10^3 Pa
d. 3.0 x 10^2 Pa
e. 3.0 x 10^5 kPa

    They already have told you the force, so divide it by the window area. The force they have quoted is the NET force (outside - inside), but they didn't tell you that. They should have.

    Force/Area = 300 Pa

    The normal (static) air pressure (which is much higher) isn't needed

    150 Pa
