Answer:
And if we compare this value with the speed limit of 35 mi/h then the police officer should believe that the motorist was not speeding, since his speed was lower than 35 mi/hr.
Step-by-step explanation:
Estimate the speed at which the motorist was traveling before braking
For this case we have the following formula for the spped of a car:
Where L represent the length and v the velocity in miles/hr.
For this case we know that a police officer measures the car’s skid marks to be 45 feet long, so then L =45 ft, and we can finde the velocity of the car replacing L=45 ft and we got:
If the posted speed limit is 35 miles per hour and the motorist tells the officer she was not speeding, should the officer believe her? Explain
