The formula for the braking distance of a car is: 0.03361v² μ d= where: .d is the braking distance (in feet) ● v is the initial velocity of the car (in miles per hour) is the coefficient of friction between the tires and the roadway At the scene of an accident, the driver tells a police officer he had been driving at 25 miles per hour when he slammed on his brakes and skidded off the road. If the road is covered in snow with a friction coefficient of μ = 0.25, how long should the skid marks be if the driver was really going 25 miles per hour? feet (Round to 1 decimal place.) The officer measures the skid marks and finds they are 147 feet long, which shows the driver was going faster than 25 miles per hour. Use d = 147 to determine the actual speed of the car. d=
