MIL-HDBK-1013/14
Scale: 1 foot per second squared = 0.3048 meter per second squared
Figure 5
Vehicle Speed vs. Acceleration Distance
To illustrate its use, consider the case of a vehicle accelerating on a 300-foot (91.5 m),
straight, horizontal path with initial speed, v0 = 25 mph (15.53 kph), and acceleration, a = 10 feet
per second squared (3.05 meters per second squared). The speed at the end of the path will be
determined as follows:
1) Locate v0 = 25 mph (15.53 kph) on the vertical axis (point A).
2) Draw a horizontal line from point A until it intersects the curve (at point B) for a =
10 feet per second squared (3.05 meters per second squared).
3) Draw a vertical line down from point B until it intersects the horizontal axis (point
C). This is the point from which velocity will be calculated.
