**Problem Statement for Rotational Kinematics**

An engine starts at 100 rad/s of angular velocity and uniformly accelerates to 400 rad/s in 9.5 seconds. Find the total angle rotated during this time, in radians (rad).

**Hint:** Use the rotational kinematics formula. Assume the initial angle is zero.

---

This problem focuses on understanding and applying the principles of rotational kinematics. If initially, the angular velocity (ω₀) is 100 rad/s and the final angular velocity (ω) is 400 rad/s, with a time duration (t) of 9.5 seconds, you can use the following kinematic equation to find the total angle (θ) rotated:

\[ \theta = \omega_0 t + \frac{1}{2} \alpha t^2 \]

Where:
- ω₀ is the initial angular velocity
- ω is the final angular velocity
- α is the angular acceleration
- t is the time duration

Since the problem involves a uniformly accelerated rotation, it's also necessary to determine the angular acceleration (α) using the formula:

\[ \alpha = \frac{\omega - \omega_0}{t} \]
