Yes, that's what I want to know. What other information do you need ?Mech_Engineer said:Do you mean estimating how fast a car was going when it hit a pedestrian and threw them down the street? I'm not sure you can estimate that using only the information provided...
To calculate using the laws of physics: the weight of the car, the weight of the pedestrian, the amount the speed of the car changed in the collision, the angle at which the pedestrian was thrown, the details of the damage done to the car in the collision including how much energy went into deforming fenders and the like, and probably some other stuff that I've overlooked.Fatlum said:Yes, that's what I want to know.

Data seems to be insufficient.Fatlum said:How can we calculate the speed of a vehicle from pedestrian throw distance ?
If the weight of a vehicle is 1220 kg and a pedestrian's weight is 72 kg. Throw distance is 20.70 meters.
The vehicle speed can be calculated using the formula: speed = distance / time. In this case, the distance is the pedestrian throw distance and the time is the time it took for the pedestrian to throw the object.
Some factors that can affect the accuracy of the calculation include the weight and shape of the object thrown, the height at which it was thrown, and any external forces such as wind. It's important to carefully consider and account for these factors in the calculation.
No, the pedestrian throw distance must be within a certain range for accurate calculation of the vehicle speed. If the distance is too short or too long, it may not provide an accurate measurement of the vehicle's speed.
The pedestrian throw distance can be measured using a measuring tape or ruler. It's important to measure from the point of release to the point where the object lands, in a straight line.
There are several limitations to this method, including the potential for human error in measuring the distance and time, the accuracy of the object thrown, and external factors that may affect the throw. Additionally, this method may not be suitable for all types of vehicles and speeds.
