Two blocks are placed at the ends of a horizontal massless board, as in the drawing. The board is kept from rotating and rests o
n a support that serves as an axis of rotation. The block on the right has a mass of 2.8 kg. Determine the magnitude of the angular acceleration when the system is allowed to rotate.
The magnitude of the angular acceleration ∝ = }[/tex]
Explanation:
The angular acceleration ∝ is equal to the torque (radius multiplied by force) divided by the mass times the square of the radius. The magnitude of angular acceleration ∝ will have the equation above but we have to replace the mass in the equation by 2.8kg as stated.
