When [theta=2/3*pi] rad, the angular velocity and angular acceleration of the circular plate are [theta_1=1.4 ] rad/s and [theta_2..=3.5] rad/s^2 respectively.
A) Determine the magnitude of the velocity of the rod AB at this instant.
B) Determine the magnitude of the acceleration of the rod AB at this instant.
Steps or solution with similar numbers would be fine.
