# A turbine rotor of radius \(R = 0.50\text{ m}\) starts from rest at time \(t = 0\) and rotates with a constant angular acceleration of \(\alpha = 4.0\text{ rad/s}^2\). What is the magnitude of the radial acceleration of a point on the outer perimeter of the turbine at time \(t = 2.0\text{ s}\)?

A turbine rotor of radius \(R = 0.50\text{ m}\) starts from rest at time \(t = 0\) and rotates with a constant angular acceleration of \(\alpha = 4.0\text{ rad/s}^2\). What is the magnitude of the radial acceleration of a point on the outer perimeter of the turbine at time \(t = 2.0\text{ s}\)?

- **A.** \(16\text{ m/s}^2\)
- **B.** \(32\text{ m/s}^2\)
- **C.** \(64\text{ m/s}^2\)
- **D.** \(128\text{ m/s}^2\)
