(a) Determine the power it takes to overcome aerodynamic drag on a small \(\left(6 \mathrm{ft}^{2}\right.\) cross section), streamlined ( \(C_{D}=0.12\) ) vehicle traveling \(15 \mathrm{mph}\).

(b) Compare the power calculated in part

(a) with that for a large (36 \(\mathrm{ft}^{2}\) cross-sectional area), nonstreamlined ( \(\left.C_{D}=0.48\right) \mathrm{SUV}\) traveling \(65 \mathrm{mph}\) on the interstate.
