Speed A + Speed B = Speed Combined

Unless they hit each other. Then, under Newton's Third Law, it's

(Speed A + Speed B) / 2 = Combined Collision Force

IE, if two cars hit each other head-on, both going 50mph, it's the same force as a single car hitting a wall at 50mph. (i.e. The impact force does not double; because you have to divide the absorption force of a second vehicle, which cancels out half of the force)

What is closing speed in a head on collision?

Closing speed in a head-on collision refers to the combined speed at which two vehicles are approaching each other before impact. It is calculated by adding the speeds of both vehicles together. The higher the closing speed, the more severe the impact and potential damage.


If two approaching vehicles are traveling at 70 mph each then their closing speed is?

Oh, dude, their closing speed would be 140 mph. Like, it's basically just adding up their speeds because they're both heading towards each other. So, yeah, if you're ever in a race with someone and you're both going 70 mph, you'll be closing in at 140 mph. Just watch out for those speed bumps, man.


If two approaching vehicles are traveling at 50 mph each their closing speed is?

100


How does perceived speed differ from actual speed when two objects are approaching each other and when they are traveling away from each other?

There is addition of the speed.


Two approaching cars are going 70 mph what is closing speed?

140 mph


When two cars approaching each other 600 km apart how speed of cars is found if the difference in their speed is 6 km per hour?

There is not enough information to answer the question.


How does the speed of the combined cars compare to the speed of the car before the collision when a parked car is hit by a moving car and the two cars stick together?

When a parked car is hit by a moving car and the two cars stick together, the combined speed after the collision will be less than the speed of the moving car before the collision. This is because some of the kinetic energy is lost as the two cars stick together due to the collision impact.


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.


If two cars hit head on and each is going the same speed is the collision speed the combined speeds?

Yes, and I saw the result of that while living in Germany. Two cars hit headon going at the same speed. It was a mess. One was a VW Beetle and there was nothing left but the back seat. They had to airlift the driver out.


What if your red side light must be visible two boats approaching from which direction?

If two boats are approaching from the port (left) side, and you have a red side light, it means they are on a collision course with your vessel. You should take immediate action to avoid a collision by altering your course or speed.


Do two vehicles travelling at the same speed cover the same distance at the same time?

Speed is measured by distance and time, yes. Velocity takes in direction.


Can two cars moving with the same speed collide?

Yes. If in opposing directions, obviously. But if they were in parallel to each other, they could still touch and damage each others bodies.However, two cars moving with the same velocity cannot collide.
