1. Sketch a position-time graph that corresponds to the description below: The object starts at a position of negative four meters • It moves at a velocity of +0.5 m/s for six seconds • The object is then at rest for three seconds • It reverses direction and moves at a speed of 0.75 m/s for four seconds • It continues at a constant speed for another two seconds so that its average velocity over the entire trip is +1/3 m/s.
