A tractor-trailer truck is coasting freely, with no brakes,down an 8° slope at 1000-m standard altitude. Rollingresistance is 120 N for every m/s of speed. Its frontalarea is 9 m2, and the weight is 65 kN. Estimate the terminalcoasting velocity, in mi/h, for (a) no deflector and(b) a deflector installed.
