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.

What is the impact speed of a car moving at 100kmh and hits a car traveling in the same direction at 98kmh?
The impact speed is just the difference between the two speeds, so in this case 2 km/hr.
A car is traveling south at a speed of 68 miles per hour and then begins traveling at a speed of 69 miles per hour but continues traveling in the same direction What has changed?
Both the speed and velocity have increased as a result of acceleration.
What is the speed in meters per second of a ship traveling at twenty knots?
10.2888888 is the speed in meters per second of a ship traveling at 20 knots.
A jet plane traveling at a speed of 82 miles per hour is traveling at what speed in meters per second?
Apart from the fact that a jet plane would stall at that low a speed, the speed is equivalent to 36.657 metres per sec
What is distance divided by rate?
to find the speed at which you are traveling
Traveling faster than the speed limit increases both the risk and the of a crash?
Traveling faster than the speed limit increases both the risk and the severity of a crash. Speeding reduces the driver's reaction time and control, making it more difficult to avoid collisions or stop safely. It also magnifies the force of impact in case of a crash, leading to more severe injuries or fatalities.
How is crash speed determined when two vehicles are moving in the same direction?
When two vehicles are moving in the same direction and collide, the crash speed is determined by the difference in speed between the two vehicles at the moment of impact. The crash speed can be calculated by subtracting the speed of the vehicle behind from the speed of the vehicle in front. This difference in speed translates to the force of impact experienced by the vehicles and occupants.
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 impact does the airplane have on the environment?
That would depend on the kind of aircraft and the speed it was traveling, at the time of "impact" on the environment.
What is designed to absorb the impact of a high speed crash?
Crumple zones,Air bags,
What is the point of impact in a crash are key factors in determining motor vehicle crash survivability?
Speed is a key factor. The higher the speed to more damage will be done. Side impact crashes are the most lethal to passengers. According to a recent Insurance Institute for Highway Safety analysis, drivers of vehicles that perform well in its side-impact crash tests are less likely to die in a crash, compared to drivers of vehicles that have received poor grades in its tests.
Why does a high speed crash cause more damage tha a low speed crash?
In a high-speed crash, there is more kinetic energy that needs to be dissipated upon impact, leading to more damage. The force of impact in a high-speed crash is also greater, causing more deformation to the vehicles and potentially more severe injuries to occupants. Additionally, the time available to decelerate in a high-speed crash is shorter, resulting in a more abrupt and intense collision.
What is the impact speed of a car moving at 100kmh and hits a car traveling in the same direction at 98kmh?
The impact speed is just the difference between the two speeds, so in this case 2 km/hr.
If you triple the speed of a car what is the rate of impact?
If you triple the speed of a car, the rate of impact in a collision will increase significantly due to the kinetic energy being proportional to the square of the speed. This means that a car traveling at three times the speed will have nine times the kinetic energy upon impact, leading to a much more severe collision.
What is the impact speed when a car moving at 100 kmh bumps into the rear of another car traveling in the same direction at 98 kmh?
The impact speed when the car moving at 100 km/h bumps into the rear of another car traveling at 98 km/h is 2 km/h. This is because the difference in speeds between the two cars is 2 km/h when they collide.
What forms when small meteorites crash into the Moon?
When small meteorites crash into the Moon, they create impact craters. These craters can vary in size depending on the size and speed of the meteorite. Over time, the accumulation of these impact craters contributes to the Moon's rugged and cratered surface.
