MP 6 :: Speed Trap
Note: Make sure to use complete sentences when completing the following assignment.
Doppler radar measures the rate of change of the distance from an object to the observer. A police officer $a$ feet from a straight road points a radar gun at a car traveling along the road, $c$ miles away, and measures a speed of $v$ miles per hour. What is the car’s actual speed?
Assume that $c = 0.25$ miles and the speed limit is $65$ mph. If the car is traveling the speed limit, is it possible for the officer to clock the car going two miles per hour over the limit?
What can you conclude from this information?
