Police and private investigators often use the laws of mathematics to determine the circumstances behind incidents. One formula that is often used in car accident reconstruction is
S is equal to the square root of 21d
The formula says that S equals the square root of 21d.
The variables are defined as follows:
S= the car’s speed (in miles per hour)
d= the length of the skid mark (in feet)
Since police have the use of calculators in the real world, you are allowed to use a calculator in this lab to help you in determining the value of some radical expressions.
If a car is traveling at 60 mph and the driver applies the brakes in an emergency situation, how much distance is required before the driver comes to a complete stop? Round your answer to the nearest foot.
