## Homework Statement

http://www.fileden.com/files/2006/11/15/381656/19.39.png [Broken]

The figure shows a hypothetical speed distribution for a sample of N gas particles (note that P(v) = 0 for speed v > 2v

_{0}).

(b) What is the value of v

_{avg}/v

_{0}?

## Homework Equations

v

_{avg}= int[vP(v)]dv

## The Attempt at a Solution

The solutions manual says that, for the triangular portion of the distribution, P(v) = av/v

_{0}.

This may be a stupid question, but how does one get that?

(only need help with that portion of the problem for now)
