Chapter 8: Q. 551RE (page 855)

An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 175 feet. Use the formula $s = \sqrt{24 d}$ to find the speed of the vehicle before the brakes were applied. Round your answer to the nearest tenth.

Short Answer

Expert verified

The speed of the vehicle before the brakes were applied is $64.8 f t / s$

Step by step solution

Given information

The length of the skid marks was 175 feet

Solution

The speed of the vehicle before the brakes were applied

$s = \sqrt{24 d} d = 175 f t s = \sqrt{24 \times 175} s = 64.8 f t / s$
