November 14, 2014 in Timbergrove: This is what a little sedan can do to a stopped SUV. Well it happened. The matriarch who is so safety conscious was hit at a stop light. Thank goodness that we were not in the vehicle. There may not be a Mr. Bud anymore because of the wreck and illness.
The guy was a real weirdo, scary. Momma is still shakin by the whole episode. The guy could not figure out how to leave the apt complex and now slammed into her. Refused to call the police because apparently did not have an insurance card, because he fled. He returned 10 minutes later with the card and his hood tied down.
Gregory St Cyr in a 2,800 pound Honda Civic 2-door sedan hit a 6000 pound SUV that was stopped at a stop light with such force that it moved the SUV 1.5 to 2 yards forward.
Why pupils maybe are constricted to look like little dots in a cloudy day.
Land Cruiser 5900 pounds
(2678 kg = 26,243.2 N = 183.5 slugs) versus
Honda Civic 2800 pounds
(1270 kg = 12,454.4 N = 87 slugs), moved braked vehicle 6 feet forward (2
meters).
35 mph=56 km/hr=15.6 m/s)
or (9 mph=14 km/hr = 3.8 m/s), on 18th St
force = mass *
acceleration
1/2mv^2= initial kinetic
energy
-1/2mv^2=work required to
stop vehicle
2631 kg * 2.5 m/s^2=6577
N
1478 pounds
If the weight of the car is
12454.4 N = 2800 lb, corresponding to
mass = 1270.857 kg = 87 slugs,
and the car is traveling with a speed:
v = 4.5 m/s = 16 km/hr = 10 mi/hr,
then a crash which stopped the car in a distance d=.3 m = 1 ft
would result in an average impact force of
mass = 1270.857 kg = 87 slugs,
and the car is traveling with a speed:
v = 4.5 m/s = 16 km/hr = 10 mi/hr,
then a crash which stopped the car in a distance d=.3 m = 1 ft
would result in an average impact force of
Impact force F = 41662 N = 9366 lb = 4.7 tons
Now multiply this impact force six times to represent the 6 feet the the Land Cruisers was moved forward at a stopped position. 28.2 tons = 56,400 pounds
