A tractor enters at a downward slope of 2 by one hundred traveling at 108 km / h and must slow down to 72 km / h in 300 m. The cab has a mass of 1 800 kg and the trailer 5 400 kg. Determine a) the average braking force to be applied, b) the average force exerted on the coupling if 70 percent of the braking force is provides the trailer and 30 percent the cab.
