# A pitot probe on an aircraft in a steady, level flight records a pressure of $55,000 \mathrm{~N} / \mathrm{m}^{2}$. The static pressure and density are $45,280 \mathrm{~N} / \mathrm{m}^{2}$ and $0.6 \mathrm{~kg} / \mathrm{m}^{3},$ respectively. The wing area and the lift coefficient are $16 \mathrm{~m}^{2}$ and 2 , respectively. The wing loading (in $\mathrm{N} / \mathrm{m}^{2}$ ) on this aircraft is____________ $\quad$ (accurate to one decimal place).

Next Question :

A spacecraft forms a circular orbit at an altitude of $150 \mathrm{~km}$ above the surface of a spherical Earth. Assuming the gravitational parameter, $\mu=3.986 \times 10^{14} \mathrm{~m}^{3} / \mathrm{s}^{2}$ and radius of earth, $\mathrm{R}_{\mathrm{E}}=6,400 \mathrm{~km},$ the velocity required for the injection of the spacecraft, parallel to the local horizon, is______________ $\quad$ (accurate to two decimal places).
