## Homework Statement

A planet has mass, 2 x 1022 kg, and radius, 2 x 106 m. Initially, its

atmosphere contains gas particles of various masses. If the gas is at temperature, 400 K,

and has a Maxwell-Boltzmann velocity distribution, what mass of particle will typically

escape from the planet’s gravitational pull? (Hint: You can just use the average velocity,

you don’t need to consider the full Maxwell-Boltzmann distribution).

## Homework Equations

vrms=sqrt(3kbT/m)

P(v)=v^2*e^(-0.5mv^2/kbT)
