Calculate Deceleration Distance



Formula

The formula to calculate the Deceleration Distance (d) is:

\[ \text{d} = \frac{v^2}{2 \times a} \]

What is Deceleration Distance?

Deceleration distance is the distance required for a moving object to come to a complete stop when a constant deceleration is applied. It is a critical factor in vehicle safety and is used to design roadways, runways, and safety systems. Understanding the deceleration distance can help in preventing accidents by ensuring that sufficient space is available to stop a vehicle safely.

Example Calculation

Let's consider an example:

Using the formula to calculate the Deceleration Distance:

\[ \text{d} = \frac{20^2}{2 \times 5} = \frac{400}{10} = 40 \, \text{meters} \]

This demonstrates that with an initial speed of 20 meters/second and a deceleration of 5 meters/second², the deceleration distance would be 40 meters.
