Chapter 14.1, Problem 14.1TYU

A body like that shown in Fig. 14.2 oscillates back and forth. For each of the following values of the body’s x-velocity v_x and x-acceleration a_x, state whether its displacement x is positive, negative, or zero. (a) v_x > 0 and a_x > 0; (b) v_x > 0 and a_x < 0; (c) v_x < 0 and a_x > 0; (d) v_x < 0 and a_x < 0; (e) v_x = 0 and a_x < 0; (f) v_x > 0 and a_x = 0.
