What is the approximate speed of a car that can knock a person 17 meters away?

In addition to being related to the speed of the car, it also has a lot to do with the weight of the vehicle. However, to knock a person 17 meters away, the speed must exceed 80 km/h. Here is an introduction about vehicle speed: 1. Introduction: The distance a car travels in a unit of time, referred to as vehicle speed. Common units are kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and plays an important role in the study of traffic flow theory. 2. Function: Vehicle speed can also generally refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly divided into spot speed, segment speed, and design speed.
I always feel that the speed of the car has a big impact on how far someone is thrown upon impact. I've heard traffic experts say that the higher the speed, the greater the momentum, and the farther a person is thrown. Being thrown 17 meters is quite a distance—it likely means the car was going at least 50-60 km/h, possibly even 70-80 km/h. But it's not a fixed value; there are many influencing factors, such as whether the road is slippery or dry, the weight of the person hit (lighter or heavier), and the weight of the vehicle itself. A small car hitting a lightweight cyclist might throw them farther, whereas a large truck might not necessarily do so. I remember my driving instructor warning me that braking becomes ineffective beyond 40 km/h, making collisions dangerous, let alone an accident where someone is thrown 17 meters! Always drive cautiously, anticipate pedestrian movements, and don't rush. Safety comes first—otherwise, both lives and property are at stake.
