Question

Hey there, I have a physics question that sadly I can't figure out since the pearson e book keeps crashing. Also I am blind and CAN'T SEE PICTURES OR GRAPHS!! So for the question: Let θ be the angle that the vector A⃗ makes with the +x-axis, measured counterclockwise from that axis. Find the angle θ for a vector that has the following components.Part AAx= 4.20 m, Ay= -2.10 mExpress your answer in degrees.

Answer 1

ANSWER:

333.4°

STEP-BY-STEP EXPLANATION:

To find angle for a vector:

$\theta=\tan ^{-1}\mleft(\frac{A_y}{A_x}\mright)$

We substitute the values of this case and the angle would then be:

$\begin{gathered} \theta=\tan ^{-1}\mleft(\frac{-2.10}{4.20}\mright) \\ \theta=\tan ^{-1}(-0.5) \\ \theta=-26.56\cong-26.6 \\ \theta=360-26.6 \\ \theta=333.4\text{\degree} \end{gathered}$

The angle is 333.4°
