Suppose that the most massive car ever built is moving down a 10.00 slope when the driver applies the brakes. The net force acting on the car as it stops is -2.00X104 N. If the coefficient of kinetic friction between the car’s tires and pavement is 0.797, find the car’s mass. What is the normal force that the pavement exerts on the car?
