Question

An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks, d, was 117ft. Use the formula s=24d−−−√ to find s, the speed of the vehicle before the brakes were applied. Round your answer to the nearest tenth.

Answer 1

53

Explanation:

Answer 2

The speed is 2808 ft/s

Explanation:

step one:

In this problem we are expected to substitute the value of d in the expression for velocity given as

`s=24d`

step two:

Given that

d= 117 ft

Substituting the value for d in the given equation we have

`s= 24*117\\\\s=2808 ft/s`

The problem basically tests our ability to perform basic substitution operation which we have performed, should you have any question or doubt, kindly respond to this question
