Angular Velocity

A rod slips with one end on x-axis and the other on the y-axis.
If the the velocity of the end on the x-axis is V when ange is theta.Find the angular velocity of the rod?

use the concept of instantaneous axis of pure rotation....

(mgl/2)sin @°=(1/2)Ipw2
w is the angular velocity
Ip=(ml2/12)+mx2
find x and u have got ur ans

arshad it is already given that at the instant of concern velocity of one end is V ..
so why have you written energy equation ! ?
and also it is not mentioned at all what kind of forces exist

@phillip wat is the wrong in writing energy equation as no external forces are acting about IAOR

@sagnik . this is a very basic problem can you tell me what is the problem you are facing..

However here is the solution .(if you can call a line a solution)
ωL sinθ = V
=>ω = VL sinθ
θ is the angle rod makes with the x axis.

@ phillip.....how can u assume pure rotation about any point other than the instantaneous axis of pure rotation.......????

I have not assumed any kind of
pure rotation about.... whatever
