As shown in Fig. P9.53a, a kayak is a relatively streamlined object. As a first approximation in calculating the drag on a kayak, assume that the kayak acts as if it were a smooth, flat plate \(17 \mathrm{ft}\) long and \(2 \mathrm{ft}\) wide. Determine the drag as a function of speed and compare your results with the measured values given in Fig. P9.53b. Comment on reasons why the two sets of values may differ.
