At an accident scene on a level road, investigators measure a cars skid mark to be 88m

Question:

At an accident scene on a level road, investigators measure a car’s skid mark to be 88m long. The accident occurred on a rainy day, and the coefficient of kinetic friction was estimated to be 0.42. Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes. (Why does the car’s mass not matter?)
