This graph shows two distinct lines. The first line is solid blue and is labeled 1.00 Miles per second while the second line is colored red and is labeled 0.25 Miles per second. The vertical axis of this graph ranges from zero to 100 and represents Force in kilonewtons while the horizontal axis of this graph ranges from zero to 180 and represents Deflection in millimeters. Both lines begin at the point of zero on both the vertical and horizontal axes. The first line, the blue line, rises to the point of 75 on the vertical axis and 70 on the horizontal axis where it then drops to the point of 48 on the vertical axis and 70 on the horizontal axis. The blue line then continues to descend unevenly to the point of 32 on the vertical axis and 100 on the horizontal axis where it then ascends gradually and leaves the graph at the points of 50 on the vertical axis and 180 on the horizontal axis. The second line, the red line, rises to the point of 75 on the vertical axis and 70 on the horizontal axis where it then drops to the point of 48 on the vertical axis and 74 on the horizontal axis. The blue line then continues to descend unevenly to the point of 32 on the vertical axis and 108 on the horizontal axis where it then ascends gradually and leaves the graph at the points of 50 on the vertical axis and 180 on the horizontal axis.
