A terrible accident in Kharkov: the blogger made accurate calculations

Страшная авария в Харькове: блогер провел точные расчетыSurfaced important details.

Ukrainian blogger Evgeny Solovyev conducted a mathematical analysis of the terrible accident in Kharkov and came to the conclusion that the driver of the Volkswagen Touareg, which runs as a witness in the case, had no chance to avoid the collision with the Lexus.

The calculations he carried out based on the video from the accident scene.

On the 4th second of the video “Lexus” passes the Children’s world, 11-th second of it at the end of the Constitution square.

The approximate distance between these points is m 230m 230 ÷ 7 ~ 33 m/sec. or nearly 120 miles per hour. – with a average speed “Lexus” crossed Constitution square.

Witnesses claim that at the time of the collision “Lexus” accelerated (i.e., they could accelerate and up to 130-140 km per hour).

The second piece (starting from the 12th second). Leaving the area with the 2nd strip bursatskiy street, “VW Touareg” slightly turns to the left about 10 degrees, because the entrance to the lane Mechnikov is slightly to the left lanes.

This means that the “Lexus” and “Volkswagen” are faced not strictly in the perpendicular line, and at an angle of 80 degrees (“Lexus” approached from this angle, with the back hemisphere relative to the motion vector of the Volkswagen).

It is clear that in the last second before the crash (in the video is the gap between 18-th and 19-th of seconds) Volkswagen crossed the distance, little more than two housings, i.e. approximately 10 m, which corresponds to a speed of 36 km per hour.

The blogger appreciated the opportunities the driver “Volkswagen” see “Lexus” for a second before the collision.

“Building a triangle, where the point – the point of impact, point a is the location of “Lexus” for a second before the collision (AC = 33 m), point To the location of the “Touareg” for a second before the crash (BC = 10 m). Given the small lapel, “Volkswagen”, the angle ACB = 80 degrees. We need to find the measure of angle ABC so we know where were supposed to look (at what angle to the direction of proper motion) the driver of “Volkswagen” to notice “Lexus”, at least for a second before the collision,” writes the blogger.

Using the theorem of cosines, it is found:

Distance of the sun = 32,8 m

The value of angle ABC = 82.5 degrees, i.e. almost at a right angle relative to the direction of movement, and clearly beyond the limits of visibility through the windshield (only through the side).

“Well, then – draw your own conclusions. Particularly drivers. As far as possible during the ride (I stress while driving and not before) to turn his head left and right, 80-90 degrees, and look at the road ahead. And if at this time the red light instead of the “Lexus” on the right to the crosswalk in front (Mechnikov) jumped a pedestrian?” says Solovyov.

According to the blogger, the argument that the approaching “Lexus” was noticed by other drivers (going for the “VW”) will not be accepted. They were about 10-15 m rear “Volkswagen” and, accordingly, the second before the accident “Lexus” quite got into their field of view (at an angle of approximately 50-60 degrees).

At the beginning of the movement “Volkswagen” (approximately 3.5 seconds before the collision) of “Lexus” was about 115-120 m away from the intersection (the light was yellow, and no reason to believe that its the driver not slowing down, will want to slip on red, was not).
