**Windmill Blade Analysis: Angular Velocity and Acceleration**

**Scenario Description:**
The blade on the horizontal-axis windmill, as depicted in Figure 1, is rotating with an initial angular velocity (\( \omega_0 \)) of 2 radians per second. It is subjected to an angular acceleration (\( \alpha_c \)) of 0.4 radians per second squared.

**Figure Description:**
- The diagram shows a windmill with a horizontal-axis. The blade, marked in blue, is labeled with point \( P \) at its tip.
- The blade length from the axis to point \( P \) is given as 15 feet.

**Part A: Angular Velocity Calculation**
- **Task:** Determine the angular velocity of point \( P \) on the tip of the blade when \( t = 4 \) seconds.
- **Expression Required:** Provide the answer in radians per second, accurate to three significant figures.
- **Current User Input:** \( \omega_P = 2.68 \) rad/s
- **Feedback:** Incorrect response. The user has 4 attempts remaining.

**Part B: Acceleration Magnitude Calculation**
- **Task:** Determine the magnitude of the acceleration of point \( P \) on the tip of the blade when \( t = 4 \) seconds.
- **Expression Required:** Provide the answer in feet per square second, accurate to three significant figures.

**Instructions for Users:**
- Use the provided diagram and details to calculate the required physical quantities.
- Ensure to follow the units specified for each calculation.
- Re-examine the calculations if the initial submissions are marked incorrect.
