![**Title:** Calculation of Particle Acceleration in Polar Coordinates
**Description:**
A particle follows a path along which the radial position is given by the equation:
\[ r = (0.2 + 0.15 \cos \theta) \, \text{m} \]
The task is to calculate the magnitude of the particle's acceleration given the following conditions:
- The angle \( \theta = 30^\circ \)
- The angular velocity \( \dot{\theta} = 0.7 \, \text{rad/sec} \)
- The angular acceleration \( \ddot{\theta} = 0.5 \, \text{rad/sec}^2 \)
**Objective:**
To determine the particle's acceleration in meters per second squared (\( \text{m/s}^2 \)) under the specified conditions.
**Instructions:**
1. Use the provided radial and angular values.
2. Apply the relevant equations for polar coordinates to find the acceleration.
3. Ensure to express the final result in \( \text{m/s}^2 \).
**Note:** Diagrams or graphs are not present in the given text.](https://content.bartleby.com/qna-images/question/12c62ea9-2423-4a35-a6cd-74646c6bbd41/1616fbaa-ee50-49e9-8a99-3e5c09c36f2d/mvubipg_processed.jpeg)
