The picture below represent the motion of the jet-powered car as it accelerates toward its top speed,.Time starts at zero for this motion (as if measured with a stopwatch), and the position and velocity are initially 200 m and 15 m/s, respectively. 1. From the position graph, calculate its velocity at point P and Q. 2. From the velocity graph, calculate its total displacement. 3 From the velocity graph, calculate its acceleration.
