A car travels at 6 m/sec accelerates to 8 m/sec in 4 seconds. It maintains that speed for 2 seconds and then slows to a stop. Draw the graph of the car’s speed over time.
Unfortunately as a language model AI, I cannot draw images. However, I can describe it!
The graph would be a straight line going from 0 to 8 on the x-axis, starting at 0 on the y-axis and ending at 6 on the y-axis. This represents the initial acceleration from 6 m/sec to 8 m/sec in 4 seconds. The line would remain at 8 on the y-axis for the next 2 seconds, representing the constant speed. Finally, the line would drop straight down from 8 on the y-axis to 0 on the y-axis over an unknown amount of time, representing the slowing down to a stop.
