Part B简答题部分

Solution to Problem 2：

(a) The force on the panel, or the rate of momentum change, is equal to the product of the number of molecules that strike the panel per unit of time with the change of mo­mentum of individual particles when they collide with the panel. Since the molecules are absorbed, they come to rest and the change is equal to the incident momentum itself.

If n is the number of molecules per unit volume, the number that strike the panel per unit of time, or flux, is equal to the product of n with the surface A of the panel and the component of the molecules’ velocity per­pendicular to the panel. The momentum of an individual incident molecule perpendicular to the panel is its mass m times the component of of its velocity perpendicular to the panel. Since nm = ω, the mass density of the molecules, this gives F = ωAv² , with v the average speed of the molecules with respect to the panel, when the flux is perpendicular to it.
