Asked by Jennifer
At an accident scene on a level road, investigators measure a car's skid mark to be 68 m long. It
was a rainy day and the coefficient of friction was estimated to be 0.40. Using the work-energy
theorem determine the speed of the car when the driver slammed on (and locked) the brakes. Why
does the car's mass not matter?
