relative speed and angular velocity

Please see the attached file. Please include all vector diagrams.

Point A of the link BA has a downward velocity of Va = 2 m/s during an interval of it's motion. For the position where ø = 30 degrees determine the angular velocity of AB and determine the velocity (Vg) of the midpoint G of the link..

Solve the relative velocity equations using :
A a vector polygon
B vector algebra


Solution Summary

It determines the angular velocity of the link by solving the relative velocity equations using two differential methods. The solution is detailed and was rated '5/5' by the student who posted the questions originally.
