Problem $4$: A drone made to look like the Planet Express ship has a mass of $3\mathrm{.}85$ kg is flying at a maximum speed of $28\mathrm{.}0m\frac{i}{h}$ in level flight when the drone's thrust is $5\mathrm{.}55$ N $.$ When the battery pack runs out it ejects and parachutes to the ground leaving the Planet Express drone, now with a mass of $3\mathrm{.}30$ kg to glide back to the ground at a glide angle of $15\mathrm{.}0.$ What will be the terminal velocity of the Planet Express drone as it glides to the ground? b$)$ If the drone has a cross sectional area of $0\mathrm{.}150m^2$ and the density of the air is $1\mathrm{.}25k\frac{g}{m^3}.$ Calculate the drag coefficient of the drone. Assume that for all parts of the problem, the drone experiences a force due to air resistance that is proportional to the speed of the drone squared.
