Chapter 2, Problem 22P

In the particle under constant acceleration model, we identify the variables and parameters v_xi, v_xf, a_x, t, and x_f − x_i. Of the equations in the model. Equations 2.13–2.17, the first does not involve x_f − x_i, the second and third do not contain a_x, the fourth omits v_xf, and the last leaves out t. So, to complete the set, there should be an equation not involving v_xi. Derive it from the others.
