Speed Estimate From Crush
This problem involves a 1984 Mustang that
struck a stopped city bus in the rear. There are no pre collision skidmarks.
The rear of the bus was vertical and appears to be nearly undamaged. Judging
from the debris and gougemark on the roadway, the bus did not move appreciably
after the collision. The crush damage to the front of the crash vehicle is found
to average 36"
A search of the NHTSA Crash Tests Database revelas a 1983 Ford Mustang that was
tested in a stationary barrier collision. The results of that 30 M/H test resulted
in an average of 20" of crush to the front to the vehicle 60" wide 3240 lb vehicle.
The questions are:
There is no further information
- Is there sufficient information presented to make a speed estimate for
the Mustang involved in this collision?
- If so, what is the estimate and how can it be calculated?
