Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_126

5/126 The sector rotates with the indicated angular quantities about a fixed axis through point \( B \). Simultaneously, the particle \( A \) moves in the curved slot with constant speed \( u \) relative to the sector. Determine the absolute velocity and acceleration of particle \( A \), and identify the Coriolis acceleration. (Referencing the provided diagram: point \( B \) is the pivot, \( C \) is the center of the slot arc of radius \( r_2 \), and \( r_1 \) is the distance between \( B \) and \( C \). Angular velocity \( \Omega \) and angular acceleration \( \dot{\Omega} \) are clockwise. Relative speed \( u \) is directed to the right at the instant shown.)
