Write the vector v in the form ai + bj, given its magnitude v and the angle  it makes with the positive x-axis.
-$$\| \mathbf { v } \| = 14 , \quad \alpha = 0 ^ { \circ }$$
A) $v = 14 \mathbf { i }$
B) $v = 14 i + 14 j$
C) $\mathbf { v } = 14 \mathbf { j }$
D) $\mathbf { v } = - 14 \mathrm { j }$

Question

Quizplus · Accepted Answer

The vector has a magnitude of 14 and makes an angle of 0 degrees with the positive x-axis, which means it is directed entirely along the x-axis. Therefore, its representation is $14\mathbf{i}$ with no $j$ component.

Write the Vector V in the Form Ai + Bj ∥v∥=14,α=0∘\| \mathbf { v } \| = 14 , \quad \alpha = 0 ^ { \circ }∥v∥=14,α=0∘

Write the Vector V in the Form Ai + Bj $\| \mathbf { v } \| = 14 , \quad \alpha = 0 ^ { \circ }$
