# Car C1 Speed Needed to Rotate C2 180 Degrees

• CLT Dude
In summary, the conversation discusses a car accident where a car (C1) hits another car (C2) from the opposite direction at a right angle. The car that was hit, C2, rotates 180 degrees. The weight of the cars is given as 3200lbs for C1 and 3400lbs for C2, and it is assumed that both cars have the same tires. The question is asked about the speed of car C1, but it is stated that this cannot be answered without more information and that it would be best to seek the help of an expert in car accident investigation. Suggestions are given for finding such an expert, such as looking in the yellow pages.

A car (C1) coming in the opposite direction hits the other car (C2) at right angle. The car which gets hit, C2 rotates in 180 degrees. What was the speed of the car C1?
Assumptions: Both cars have same tyres. W of C1 =3200lb (2012 Honda Accord)
w of C2=3400lb (Hyundai Tuscon)
Please let me know if you need any info.

That is impossible to answer without much more information. As this looks like a real case: ask an expert. They exist for a good reason, and their judgment can be used - unlike statements found in internet forums.

Thank you for the response. How do I ask an expert?

Find one in the yellow pages?

Edit: too slow.

Great minds think alike!

I found many. But most companies work with insurance com and not with individuals.

## What is the formula for calculating the speed needed to rotate one car 180 degrees?

The formula for calculating the speed needed to rotate one car 180 degrees is: speed = (2 x pi x radius) / time.

## What is the relationship between the speed and radius of rotation for two cars?

The relationship between speed and radius of rotation for two cars is inverse. This means that as the radius of rotation increases, the speed needed to rotate the car decreases. Similarly, as the radius of rotation decreases, the speed needed to rotate the car increases.

## How does the time taken to rotate the car affect the required speed?

The time taken to rotate the car has a direct impact on the required speed. The shorter the time, the higher the speed needed to rotate the car 180 degrees. This is because a higher speed will cover a greater distance in a shorter amount of time, allowing for the car to complete a full rotation.

## What factors can affect the speed needed to rotate one car 180 degrees?

The speed needed to rotate one car 180 degrees can be affected by various factors such as the weight and size of the car, the type of surface it is rotating on, and the amount of friction present between the car and the surface.

## What are some real-life applications of this concept?

This concept is applicable in various real-life situations such as designing roller coasters, calculating the speed of a spinning top, and determining the speed needed for a car to drift around a corner in a car race.
