Question

An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 245ft. Use the formula s=√24d to find the speed of the vehicle before the brakes were applied. Round your answer to the nearest tenth.Provide your answer below:____feet per second

Answer 1

The formula given is;

$s=\sqrt[]{24d}$

We can now input the distance d, to obtain;

$\begin{gathered} s=\sqrt[]{24\times245} \\ s=76.7ft\text{ /s} \end{gathered}$

Therefore, the speed of the vehicle before the brakes were applied is 76.7ft/s
