Short Answer

A force of 5.3 N is needed to hold on to an umbrella in a strong wind.If the air molecules each have a mass of 4.7 ×10^-26 kg,and each one strikes the umbrella (without rebounding)with a speed of 2.0 m/s in the same direction,how many molecules strike the umbrella each second? Assume that the wind blows horizontally so that the gravitational force exerted on the air molecules can be neglected.
