Exhaust (assumed to have the properties of standard air) leaves the 4-ft-diameter chimney shown in Video V5.4 and Fig. P5.42 with a speed of \(6 \mathrm{ft} / \mathrm{s}\). Because of the wind, after a few diameters downstream the exhaust flows in a horizontal direction with the speed of the wind, \(15 \mathrm{ft} / \mathrm{s}\). Determine the horizontal component of the force that the blowing wind exerts on the exhaust gases.
