Question

Transcribed Image Text:The image contains a diagram and a list of angle options related to vector directions.
**Diagram Explanation:**
- There are three vectors labeled as \( \vec{A} \), \( \vec{B} \), and \( \vec{C} \).
- The vectors originate from a common point, with coordinate axes marked as \(-x\) and \(-y\).
- \( \vec{A} \) makes an angle \(\alpha\) with the \(-x\) axis.
- \( \vec{B} \) makes an angle \(\beta\) with the \(-x\) axis.
- \( \vec{C} \) is pointing directly downward along the \(-y\) direction.
**Angle Options:**
- \( \theta_R = 185^\circ \)
- \( \theta_R = 257^\circ \)
- \( \theta_R = 174^\circ \)
- \( \theta_R = 344^\circ \)
- \( \theta_R = 67.9^\circ \)
- \( \theta_R = 270^\circ \)

Transcribed Image Text:**Displacement and Direction in Vector Analysis**
A student on a treasure hunt undergoes three displacements in search of the treasure, as shown below. The displacements' magnitudes and angles are:
- **A** = 14.9 m, **α** = 15.0°
- **B** = 16.5 m, **β** = 58.0°
- **C** = 42.5 m, angle as shown in diagram
**Question**: What is the direction angle θ_R of the resultant vector? Give the angle as measured counterclockwise from the +x axis. (Consider the vector components)
**Diagram Explanation**:
The diagram shows the three vectors on a 2D plane with an x and y axis:
- Vector **A** is positioned in the second quadrant, forming an angle α with the -x axis, indicating a displacement at 15.0° relative to the negative horizontal direction.
- Vector **B** is in the first quadrant, forming an angle β with the +x axis, indicating a displacement at 58.0° relative to the positive horizontal direction.
- Vector **C** is oriented vertically downward along the -y axis in the fourth quadrant, with its angle indicated relative to the +x axis.
The task is to determine the resultant angle θ_R of these combined displacements as measured counterclockwise from the +x axis.
