Does Crash severity increases with the speed of the vehicle at impact?
Yes, all things being equal, crash severity does increase proportional to the speed of each vehicle at impact, and is a vector sum. So, there is a big difference between crash severity at impact from being "rear-ended" (when one vehicle is traveling the same direction as another, and impacts the front of their vehicle with the rear of another) and a "head-on" impact (two cars traveling into one another, impacting both front bumpers). In the rear-end impact, you take the momentum (mass times velocity) of the rear, impacting vehicle "A" and subtract the momentum of the front-most impacted vehicle "B", and that gives you the resultant impact force (the difference in momentum being transferred). weak impact scenario example: vehicle A is traveling 60 mph, and vehicle B is the same mass and is traveling 50 mph. The difference in momentum would be the mass times 10 mph...not much. severe impact scenario: vehicle A is traveling 70 mph, and vehicle B is at rest (0 mph)...large impact. In the head-on impact, you have the most severe crash scenario. In this case, you ADD the momentum of vehicle A with the momentum of vehicle B, and you get the resultant force of impact. Even if both vehicles are traveling 30 mph, with the same mass, and have a heaad-on collision, the is close to the same as one vehicle traveling 10 mph and hitting the other vehicle going 70 mph...severe impact.
What is the effect on force if the velocity changes from 5 mph to 10 miles per hour?
Velocity does not affect force.
What is the equivalent to 70 knots in mph?
1 mph = 0.868976242 knots70 times .869 = 60.83, so just over 60mph
How many mph equal one G force?
You can not equate miles per hour to G forces. If you were traveling at 1000 mph, for example, but at a constant speed, you would fell no extra force since you are not accelerating.
What is the equivalent of 9 kilometres per hour in miles?
9 kph = 5.6 mph
Is Being in a crash at 30 MPH the equivalent force of being dropped off a four story building?
no
Being in a crash at 30 MPH has the equivalent force of being dropped off a four story building?
true
Is being in a crash at 30 mph equivalent to being dropped from a 4 story building?
Pretty close.
Is Being in a crash at 30 MPH has the equivalent force of being dropped off a four story building?
well if you were dropped off a 4story building you would probly die but a car crash is kinda different so i guess you would die in a car crash if you were a little kid but if you arent then i don't think you will
Is Being in a crash at 50 MPH the equivalent force of being dropped off a four story building?
Sort of. Imagine: You are sitting in your car, a crane lifts it up by the back bumper so that the front bumper is Fourty feet off the ground. When the crane dropps you it will hit at the same speed as a 50 mph crash. Go up four floors and look down to get an idea of why the comparison is used.
Is it true that being in a crash at 30 mph has the equivilent force of being dropped off a four story building?
Yes, its true. I had driver's ed, and my teacher explained to us the mechanics.
The force with which a body moving at 30 mph hits a dashboard is equivalent to the force of that same body hitting the ground after a fall?
... of about 61 feet.
How fast did jorge lorenzo crash?
173.8 mph
A train leaves a station at 123 mph and another leaves a train at 345 mph will they crash?
no
What does a 65 mph car crash do to the body?
It blood hurts!!
If 2 identical cars crash and each is traveling at 50 mph is the impact speed 50 mph or 100 mph and why?
The impact speed for each car is 50 mph. During the crash, both cars are accelerated from a speed of 50 mph to zero, hence the impact speed is 50 mph. The relative speed between each car, however, is 100 mph.
A 60 crash is as great as a 30mph crash?
A lot, lot worse than a 30 mph crash, as the crashing object will take longer to stop.
