Constant Acceleration -- Equation for Vavge

[QUOTE="Danger Mouse, post: 6269229, member: 670738"] [B]Homework Statement:[/B] I've recently started Sears and Zemansky's "University Physics"... Everything was fine until pg. 42. [B]Relevant Equations:[/B] ... Initially we are given the statement V[SUB]av[/SUB] = (x-x[SUB]0[/SUB])/t, so far so good. But, we encounter the following paragraph... "We can also get a second expression for V[SUB]av[/SUB] that is valid only when the acceleration is constant, so that the v-t graph is a straight line (as in Fig 2-14 - [I've omitted the graph here, it's a v-t graph with constant acceleration]) and the velocity changes at a constant rate. [I]In this case the average velocity during any time interval is imply the arithmetic average of the velocities at the beginning and end of the interval[/I]." For the time interval from 0 to t: V[SUB]av[/SUB] = (v[SUB]0[/SUB] + v)/2 I can't for the life of me figure out where the above equation comes from. My Apologies if homework is the wrong place for this. [/QUOTE]
