13–14. The 2-Mg truck is traveling at 15 m/s when thebrakes on all its wheels are applied, causing it to skid for adistance of 10 m before coming to rest. Determine theconstant horizontal force developed in the coupling C, andthe frictional force developed between the tires of the truckand the road during this time. The total mass of the boat andtrailer is 1 Mg.
