Learn how to find an object’s instantaneous speed or velocity in three ways - by using calculus, by looking at the slope of a given point on a graph of an object’s rate vs. time, or by using kinematic formulas if the object’s acceleration is constant.
Learn about kinematic equations and how to use them to analyze motion with constant acceleration.

Let's derive the drift velocity formula (v = eEt/m), in terms of relaxation time. Drift velocity is the average velocity with which, the electrons drift in the opposite direction of the field. We start with the acceleration of the electrons, a = F/m = eE/m.

For calculating the final vertical velocity, is it possible to use the formula: displacement=((initial velocity + final velocity)/2)*change in time? After substituting all the known values in, I get the result −26.017 which is only slightly different from Sal's result.
