Police use the formula to estimate the speed of a car just before it skids. in this formula is the speed of the car, is the distance the car skidded in feet, and represents the coefficient of friction. the value of depends on the condition and type of road surface. we know when the road is wet concrete and 0.95 on a dry concrete road. you are given the job of investigator! you will be given the measurements of two skidding cars involved in an accident. determine the speed of each car prior to the skid. car a: skid was measured to be 32 feet. car b: skid was measured to be 43 feet.
a. what is the exact speed in radical form and exponential form?
b. what is the estimated speed rounded to the nearest tenth?
c. you know that you should keep a safe following distance when following other cars on a roadway. how long should your following distance be if both you and the car in front of you are travelling at 55 mph?
