Web17 May 2016 · The one dimensional Maxwell distribution for the i − component of the velocity vector is f 1 D ( v i) = ( m 2 π k T) 1 / 2 exp ( − m v i 2 2 k T) Let's drop the i and 1 D subscripts for simplicity. You are looking for the average of the absolute value of v, v . To find v , we have to perform the integration ∫ − ∞ ∞ v f ( v) d v Web12. A boy runs along a straight horizontal track. The graph shows how his speed v varies with time t. After 15 s the boy has run 50 m.
