Homework Statement
If you suddenly cut the string, the rod will swing down. Find the linear velocity (V) of
the point P just before the rod hits the wall (the momentum-of-inertial I=(1/3)ML^2 if the rod rotates about the end point Q. L is the rod length and M is the rod mass).
The rod has a mass of 1kg.

Homework Equations
I=(1/3)ML^2
The Attempt at a Solution
I've found the tension on the string and the force at point Q.(.433kg and .375kg respectively).
For the linear velocity can I just find the center of mass (0.5m), treat it like a particle attached to a massless string and use v=sqrt(2*g*h)?
Or is my logic totally flawed? Any help would be great!
