When a car skids to a stop, the length L, in feet, of the skid marks is related to the speed ?S, in miles per hour, when the brakes were applied. The formula is
.
?
A: If the skid marks are 224 feet long, how fast was the car going when the brakes were applied?B: If your speed doubles, how is the skid mark length affected?C: You are driving at 69 miles per hour. You wish to slow to a speed that will cut the length of potential skid marks in half (thus reducing the emergency stopping distance). What should be your new speed?
?
Round your answer to two decimal places if necessary.
