cm/s, km/h, km/h.

4. Describe the speed-time graph of an object that is not moving.

flat line along the axis representing time.

5. Describe the motion of the object whose position-time graph is shown below.

The object was accelerating from a stop.

6. Calculate the slope of the line on a position-time graph for a car that starts at the origin at 0s and moves at a constant velocity for 15 s to a position 300 m from the origin.

20 m/s
