Question

You are in charge of an accident reconstruction case for the local police department. In order to determine car speeds, skid mark lengths are measured. To determine the coefficient of kinetic friction, you get into an identical car, and at a speed of 65.2 mi/h, you lock its brakes and skid 51.5 m to rest.
(a) Determine the car’s deceleration.
(b) What is the coefficient of kinetic friction between the tires and road surface?
(c) The car in the accident actually skidded 57.3 m. What was its initial speed?
