Total traslational kinetic energy problem

  • #1

Homework Statement


What is the total translational kinetic energy in a classroom filled with nitrogen at 1.01 x 10^5 Pa and 20.7 degrees C? The dimensions of the classroom are 4.60 m x 5.20 m x 8.80 m.


Homework Equations



Translational kinetic energy can be expressed as
Et = 1/2 mv2 (1)
where
Et = kinetic translation energy (Joule, ft lb)
m = mass (kg, slugs)
v = velocity (m/s, ft/s)
one slug = 32.1740 pounds (as mass) - lbm


The Attempt at a Solution


this is as far as i got..

use the Maxwell–Boltzmann distribution formula...that is the equation you need to use.
