**Educational Content Transcription** --- **Figure Description:** The image shows a mechanical setup involving a wheel, a rod, and a slider block. The slider block moves with the motion shown, where: - \( r = 140 \, \text{mm} \) - \( h = 500 \, \text{mm} \) The wheel is labeled at point \( A \) and is connected to a point \( B \) on the slider block. The velocity (\( v_B \)) and acceleration (\( a_B \)) at point \( B \) are given as: - \( v_B = 4 \, \text{m/s} \) - \( a_B = 2 \, \text{m/s}^2 \) **Problem Description:** **Part A** Determine the angular velocity of the wheel at this instant measured counterclockwise. - Express your answer using three significant figures. - Enter a positive value if the angular velocity is counterclockwise and a negative value if the angular velocity is clockwise. Input Interface: - Angular Velocity (\( \omega \)) = [Input Box] rad/s - Button: Submit - Link: Request Answer **Part B** Determine the angular acceleration of the wheel at this instant measured counterclockwise. - Express your answer using three significant figures. - Enter a positive value if the angular acceleration is counterclockwise and a negative value if the angular acceleration is clockwise. Input Interface: - Angular Acceleration (\( \alpha \)) = [Input Box] rad/s\(^2\) - Button: Submit - Link: Request Answer --- This content explains how to calculate the angular velocity and acceleration of a wheel system in motion. Calculations should account for the direction of motion (counterclockwise or clockwise) when inputting results.
