The site from which an airplane takes off is the origin. The x axis points east; the y axis points straight up. The position and velocity vectors of the plane at a later time are given by: $\overrightarrow{\mathbf{r}}=\left(1.61 \times 10^{6} \tilde{\mathbf{i}}+3.00 \times 10^{3} \hat{\mathbf{j}}\right) \mathrm{m}$ and $\overrightarrow{\mathbf{v}}=(150 \hat{\mathbf{i}}+21 \hat{\mathbf{j}}) \frac{\mathrm{m}}{\mathrm{~s}}$ .The plane is most likely:
A)just touching down.
B)in level flight in the air.
C)ascending.
D)descending.
E)taking off.
