# Calculating All Vector Components

CLMECH-FMZ3JA

The z-component of the vector $\mathbf{V}$ is twice as large as its projection on the xy-plane.

Compute the angle $\phi$ that $\mathbf{V}$ makes with the z-axis and all the components of $\mathbf{V}$.

A

$\mathbf{V} = \langle 1.2, 5, 5.8 \rangle$
$\phi = 26.6^o$

B

$\mathbf{V} = \langle 2.9, 5, 11.55 \rangle$
$\phi = 26.6^o$

C

$\mathbf{V} = \langle 2.9, 5, 11.55 \rangle$
$\phi = 30^o$

D
