Ladder Sliding Solution
The velocity of any point on a rigid body can be expressed as:
This vector equation can be represented graphically since the orientation of all 3 vectors are defined by the geometric constraints of the problem.
Use trigonometry to relate the magnitude of these velocity vectors.
VB = VA tanq, VB/A = VA / cosq
The angular velocity can also be found since VB/A = rB/A wAB
