**Title: Analyzing Angular Motion in a Rotating Tire**

**Diagram Description:**

The image illustrates a car tire in motion with several labeled components relevant to angular motion. The tire has a center point labeled "O" and a point on the outer edge labeled "A." A radius "r" extends from point O to point A in a direction forming an angle "θ" with a reference line. The angular velocity of the tire is denoted as "ω," rotating clockwise. Additionally, an angular deceleration, labeled "α," is acting in the opposite direction.

- **Angle θ**: The angle formed between the radius and the horizontal reference.
- **Radius r**: The distance from the center O to point A.
- **ω (Angular Velocity)**: Represents the rate of rotation of the tire in radians per second.
- **α (Angular Deceleration)**: Represents the rate of decrease of angular velocity in radians per second squared.
- **Coordinate Axes**: The x and y axes are provided for Cartesian reference.

**Technical Information:**

- **Angular Rotation**: \(\omega = 10 \, \text{rad/s}\)
- **Angular Deceleration**: \(\alpha = 15 \, \text{rad/s}^2\)
- **Radius of the Tire (r)**: \(0.55 \, \text{m}\)
- **Angle (θ)**: \(42^\circ\)

**Problem Statement:**

a. Calculate the acceleration of point A, represented as a Cartesian vector:
\[
\vec{A}_A = \left( \, \_\_\_ \, \right) \hat{\imath} + \left( \, \_\_\_ \, \right) \hat{\jmath} \, \frac{m}{s^2}
\]
