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}?

2. Relevant equations

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

3. 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)
