A Force of 5 $4.7 \times 10 ^ { - 26 } \mathrm {~kg}$

question 71

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 $4.7 \times 10 ^ { - 26 } \mathrm {~kg}$ and each one strikes the umbrella (without rebounding) with a speed of 2.0 m/s in the same direction, how many atoms strike the umbrella each second? Assume that the wind blows horizontally so that the gravity can be neglected.
