Question

What goals do investigators have when examining a car accident? How do they know how fast a car that was involved in an accident was going?

Answer 1

Investigations of car accidents aim to determine the cause, assess damage and injuries, and gather evidence. Investigators use physical evidence and calculations to estimate the car's speed during the accident.

Step-by-step explanation:

When examining a car accident, investigators have several goals. They aim to determine the cause of the accident, assess the extent of damage and injuries, and gather evidence for potential legal proceedings. They use various techniques such as analyzing skid marks, damage patterns, and witness testimonies to reconstruct the accident and determine the factors involved.

To estimate how fast a car was going during an accident, investigators use a combination of physical evidence and calculations. Skid marks, deformation of vehicles, and damage patterns can provide clues about the car's speed. Investigators can also use physics principles such as momentum and energy conservation to calculate the car's initial velocity at the time of the accident.

Answer 2

--->The goals of the investigators is to prevent tampering with evidence and reduce exposing workers to additional harm.

--> The investigators are able to find out how fast a car that was involved in an accident was going by measuring the length of skid marks.

Step-by-step explanation:

Automobile or car accidents are incidents which when it occurs are generally fast, violent and confusing to both the people involved and the eyewitnesses. With the development in technology, investigators (usually known as forensic investigators) use a variety of tools and physical evidence to put together a clear picture of what happened during a car accident. With their discoveries, they would be able to to prevent tampering with evidence and reduce exposing workers to additional harm.

They can know how fast a car that was involved in an accident was going by:

--> Analysing a physical evidence such as measurement of the length of skid marks. When the skid distance (which is the drag factor due to road surface friction) and the braking efficiency are determined, the minimum speed of a car as it started skidding can be estimated. Even the appearance of the skid mark also tells investigators whether a car was braking, accelerating, or sliding.
