Expert Solution

Step 1

The given vectors,

$\begin{array}{rcl} \vec{A} & = & 16.5 m at 48 ° \\ \vec{B} & = & (- 12.7 \hat{i} + 2.30 \hat{j}) m \end{array}$

The x and y components of A vector,

$\begin{array}{rcl} A_{x} & = & (16.5 m) \cos (48 °) \\ = & 11.04 m \\ A_{y} & = & (16.5 m) \sin (48 °) \\ = & 12.26 m \end{array}$

Step 2

So, the vector A in unit vector form

$\vec{A} = (11.04 \hat{i} + 12.26 \vec{j}) m$

The x and y components of B vector,

$\begin{array}{rcl} B_{x} & = & - 12.7 m \\ B_{y} & = & 2.30 m \end{array}$

Step 3

The H vector,

$\vec{H} = \vec{B} - 3 \vec{A}$

Substitute,

$\begin{array}{rcl} \vec{H} & = & (- 12.7 \hat{i} + 2.30 \vec{j}) m - 3 (11.04 \hat{i} + 12.26 \vec{j}) m \\ = & (- 45.82 \hat{i} - 34.48 \vec{j}) m \end{array}$
