This is my first time here, so if I put this in the wrong place I am sorry. I will place the entire problem here, exactly as it appears. The most massive car ever built was the official car of the General Secritary of the Communist Party in the former Soviet Union. Suppose this car is moving down a 10.0 degree slope when the driver suddenly applies the brakes. The net force acting on the car as it stops is -2.00 X 10^4 N. If the coefficient of kinetic friction between the car's tires and the pavement is 0.797, what is the car's mass? What is themagnitude of the normal force that the pavement exerts on the car? I have no clue as to what equations to use. Sorry. I made a free-body diagram, but I think I messed it up. Thank you for your time.
