The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. Find the terminal velocity (in meters per second and kilometers per hour) of an $$86.5\mathrm{kg}$$ skydiver falling in a pike (headfirst) position with a surface area of $$0.130{\mathrm{m}}^2$$. (Assume that the density of air is $$1.21\mathrm{kg}/{\mathrm{m}}^3$$ and the drag coefficient of a skydiver in a pike position is 0.7.) $$\begin{array}{l}\mathrm{m}/\mathrm{s}\\ \mathrm{km}/\mathrm{h}\end{array}$$
