**Problem: Grinding Wheel Rotation** A grinding wheel with a diameter of 0.39 meters rotates at 1900 revolutions per minute (rpm). **Part A: Angular Velocity Calculation** - **Objective**: Calculate its angular velocity in radians per second (rad/s). - **Instructions**: Express your answer using three significant figures. Formula to use: \(\omega = \frac{2\pi \times (\text{Revolutions per minute})}{60}\) **Input Box**: Fill in the angular velocity in rad/s. **Part B: Linear Speed Calculation** - **Objective**: Determine the linear speed of a point on the edge of the grinding wheel. - **Instructions**: Express your answer to two significant figures and include the appropriate units. Formula to use: \(v = \omega \times r\) Where: - \(r\) = radius of the wheel (half the diameter) - \(\omega\) = angular velocity from Part A **Input Box**: Fill in the linear speed in the appropriate units.
