55 mph.. the unbelted occupants would be traveling at 55 mph at the moment of impact. And, just after the vehicle come to a complete stop, the occupants will slam into the steering wheel, windshield, dashboard, c or other interior surfaces.

"Second impact syndrome" occurs when a person with a concussion, even a very mild one, suffers a second blow before fully recovering from the first.
Direct impact on students of biotechnology 'they tend to see deep till cell level and have much more understanding about living being as an organism.' Indirect impact on people who even don't know what it is 'People take in biotechnological products in the form of drug and food in daily life!"
A bad collision.
In an impact like that, the body travels with the speed of the vehicle. That means that your body will impact the dash or the windshield immediately after the vehicle impacts the wall. In any case it is about 0.1 sec from the time of impact, depending on the speed of the vehicle impacting the wall.
55 mph. If the car stops (impact) people inside are still moving at 55 mph. They will hit the inside of the car- at 55 mph. That has the same effect as if you were standing still, and were hit by a car moving 55 mph. Messy. Wear your seatbelt.
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.

crumple zones allow vehicles to absorb impact forces, transferring less energy to the occupants
Depends on the weight of the vehicle.
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
Yes, vehicles are designed with both plastic and elastic values to absorb energy forces in a manner that will reduce the direct forces that reach the vehicle occupants. The plastic materials are designed to absorb the initial impact of a collision, while the elastic materials are designed to absorb the remaining energy from the collision and dissipate it over a longer period of time. This two-step process helps to reduce the overall force that is transferred to the occupants of the vehicle.
To help minimize the effect of an impact on occupants
Is The amount of energy absorbed by a vehicle in an impact is related to the direction of the impact and design of the vehicle
The amount of energy absorbed by a vehicle in an impact is related to:
