A graph titled Position versus time for with horizontal axis time (seconds) and vertical axis position (meters). The line runs i
n 3 straight segments from 0 seconds 0 meters to 4 seconds 12 meters to 6 seconds 12 meters to 12 seconds 0 meters. Use the graph to determine the instantaneous speed at 2 seconds.
According to the graph, the distance at 2 seconds is 6 m.
<u>The speed is:</u>
s = 6/2 = 3 m/s
Total distance is 12 m between zero and 4 seconds and 12 m between 6 and 12 seconds, there is no movement between 4 and 6 seconds. and total time is 12 seconds.
