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

Answer:

The speed is 2808 ft/s

Step-by-step 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
