Question

These graphs show the position, velocity, and acceleration of an object. Note that t = 0.6 and t = 3.4 s are indicated on each of the plots. Which of the following statements is correct? From 0 to 0.6 s, x is increasing but at a slower and slower rate. During this same time interval, v decreases. At 0.6 s, both v and a are 0. Between 0.6 and 1 s, the velocity is negative because the acceleration is approaching 0. In addition, the graph of x in this region is a curve that is slowly approaching a straight line. Between 1 and 3.4 s, a is 0, v is constant, and the value of Delta x/ Delta t is constant. From 3.4 s on, the acceleration is positive, v increases linearly, and the value of x decreases linearly.
