Question

An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 84 feet. What was the speed of the vehicle before the brakes were applied?

Answer 1

Explanation:

`\sf Speed = √(24d)`

Here, d is the length of the skid marks.

`\sf Speed = √(24*84)\\`

`\sf = √(2016)\\\\= 44.9 \ feet \ per \ hour`
