A 2,000 kg car is traveling at a rate of 40 m/s when an external force of 22,750 N, opposite in direction to the motion, caused a quarter reduction of speed, what is the coefficient of kinetic friction when the force was applied for 3 seconds? What is the work done by the force in decelerating the car?
