A car initially traveling at speed 60 mi/h on a horizontal road comes to rest over a distance of 40 meters after the brakes are applied, and the magnitude of the average braking force is 1.1 x 104 N. (This is also the net force, taking all retarding forces into account.)

(a) What is the net work done on the car in stopping it? (Answer in Joules.)

(b) What is the mass of the car?
