Which of the position versus time graphs below matches the following description: a speed versus time graph has a horizontal line at 5 m/s from zero to five seconds?
Group of answer choices
A Position versus Time graph is shown with y-axis labeled position in meters up to 15 and x-axis labeled time in seconds up to 5. The points plotted are 0, 10 and 1, 10 and 2, 10, and 3, 10, and 4, 10, and 5, 10. A horizontal line connects the points.
