Velocity and acceleration of sliding of bar through the swivel

Question

In the figure shown, the end A of a bar AB, is constrained to move along vertical path AD and the bar passes through a swivel bearing pivoted at C. When A has a velocity of 3 m/s towards D and an acceleration of sliding of bar through the swivel,

1. Velocity and acceleration of sliding of bar through the swivel,
2. Angular velocity and angular acceleration of AB.

 

Answer 1

velocity and angular velocity of the sliding bar is

acceleration and angular acceration
