Current Attempt in Progress

The $0\mathrm{.}2-lb$ projectile $A$ is subjected to a drag force of magnitude $k{v}^2,$ where the constant $k=0\mathrm{.}0003lb-s\frac{e{c}^2}{f{t}^2}.$ This drag force always opposes the velocity v $.$ At the instant depicted, $v=735f\frac{t}{sec,}=49,$ and $r=330ft.$ Determine the corresponding values of $\frac{?}{\text{b}\text{a}\text{r}}(r)$ and $\frac{?}{\text{b}\text{a}\text{r}}().$

Answers:

$\frac{?}{\text{b}\text{a}\text{r}}(r)=,f\frac{t}{se{c}^2\frac{?}{b}}$
