7. A man starts at the starting line, walks back slowly and steadily for 6 seconds. Then he stands still for 6 seconds, then walks forward steadily about twice as fast for 6 seconds. Sketch the d vs t and v vs t graphs showing this motion. 8. A car is traveling down the road. It's v vs. t graph is shown below. Sketch the d vs t graph that shows the motion? 9. A car moving forward but the brakes are applied. Sketch the d vs t graph of this motion? Show some tangent lines on your graph showing fast, slower, stopped
