WebApr 22, 2008 · Average velocity is the displacement divided by the time it takes to travel that displacement. Your problem doesn't give the distance or the time, but it does say that 1/2 of the displacement is traveled at each velocity. Since velocity is constant, D/2 = v1*t1 and D/2 = v2*t2. You want the average velocity, that is v_avg = D/total_time. WebThe instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t: v ( t) = d d t x ( t). 3.4. Like average velocity, instantaneous velocity is a vector with dimension of length per time.
