Problem $2$

A drone flies at an altitude where $=1k\frac{g}{m^3}$ at a speed of $80\frac{m}{s}.$ Its wings have a planform

area $s=4m^2.$

The wings create $3\mathrm{.}2$ kN of lift. If the coefficient of drag is $0\mathrm{.}03,$ find:

The drag force

The glide ratio

Problem $3$

If problem $2$ takes place on a standard day, what is the altitude $($to $3$ significant digits$)?$

can you please help with both parts
