A van came around a corner a hit me as I gently pulled off in a small car to help my court case we measure I was pushed over 40 meters How can I give an idea as to how fast he must have been travelling? Unfortunetly it is on the Isle of Man on a no speed limit road however it is to prove that I stopped and checked and had no chacne of him hitting me with the speed in which he was travelling? Thank you

To estimate the speed at which the van was traveling, you can use the measurement of how far you were pushed. Here's an explanation of how you can calculate an approximate speed based on the distance traveled:

1. Determine the time it took for the van to push your car over 40 meters. If you have an estimate of how long this took, note it down.

2. Now, convert the time into seconds. For example, if the estimate was in minutes, multiply the minutes by 60 to get the number of seconds.

3. Next, calculate the velocity. Velocity is defined as the distance traveled divided by the time taken. In this case, the distance is 40 meters and the time is in seconds.

Velocity (in meters per second) = Distance (in meters) / Time (in seconds)

4. Calculate the speed. The speed is the velocity converted into a more common unit like kilometers per hour (km/h) or miles per hour (mph).

Speed (in km/h) = Velocity (in meters per second) * 3.6
Speed (in mph) = Velocity (in meters per second) * 2.237

Note: This calculation will provide you with an approximate speed based on the distance traveled. Keep in mind that other factors like road conditions, friction, and the weight of the vehicles involved may affect the result. It's always best to consult with an expert or attorney familiar with accident reconstruction to get an accurate analysis for your court case.
