After an accident, how do police determine the speed of which the car had been traveling?

After an accident, how do police determine the speed of which the car had been traveling? The formula, R(s) = 2V5s can be used to approximate the speed rate, R(S), in mph of the car that has left a skid (s) mark in feet.

a) Using this formula how far will a car skid at 75 mph? 

Solutions

Expert Solution

Here R(s) is the speed of car . S is the skidded mark length in feet .

given

given speed of car is 75mph . We need to find s at this speed.
Put R(s)= 75 in equation and find S

square both sides

answer

281.25 feet

In a study investigating the effect of car speed on accident severity, the vehicle speed at impact was recorded for 5000 fatal accidents. For these accidents, the mean speed was 42 miles per hour with a standard deviation of 15 miles per hour. Assuming the speeds are normally distributed, use the empirical rule to answer the following: a) About what percent of vehicle speeds were between 42 and 72 miles per hour? b) About what percent of vehicle speeds were...
