$u_t=0,u_d=r$

where $e$ is the magnitude of the angular velocity $($ vec$()$ points in the s$-$direction$).$ For the case with $m=1\mathrm{.}5s^{-1}.$ plot a contour plot of velocity magnitude $($speed$).$ Specifically, draw curves of constant speed $V=0\mathrm{.}5,1\mathrm{.}0,1\mathrm{.}5,2\mathrm{.}0,$ and $2\mathrm{.}5\frac{m}{s}.$ Be sure to label these speeds on your plot. Help me with this pls
