I was recently forwarded a link that shows two black&white pictures of an horrible accident - a pedestrian getting thrown in the air by a car. You can click on the link (bottom of message, below), to see the pictures.
Note: although the image is not gorey, it may be disturbing to some. Please exercise discretion before clicking the link.
So, my question is one of forensics: how fast was the car going when the driver blew through the red light, and what is the likelihood that the pedestrian survived?
As far as change in time goes, I cannot interpret the numbers across the top of the photograph. As best I can make out, the offending vehicle traveled from the first set of dotted lines to the third set of lines (thus giving change in distance), which corresponds with the time it took for the pedestrian on the far left to partially complete her step and recoil aghast, which may correspond with the position of the windshield wiper blade on the offending vehicle. This may not be an accurate presumption b/c the victim may have grabbed on to the wiper blade; also, none of the other cars have their wipers on (which does not preclude that our less-than-observant offender could have had the wiper on). Either an appraisal of the human stride and reaction time and/or the average speed of 1/2 cycle of a Mercedes Benz wiper blade would provide an estimate of the time...right?
It looks like the car hit the pedestrian such that his left leg completely buckled and continued to apply force at an angle such that he "glanced off" the hood, hitting his head as the car continued to pass. What would be the force of impact on his head? Did his abdomen suffer trauma, too?
How would we analyze this to assess the pedestrian's outcome?
-F.
