1just use the fact that velocities of both the ends along the length of the rod are same. (because rod can't expand)
Q. A rod is placed tilted like a ladder is placed having its contact with ground as well as with the perpendicular wall.
the rod is making an angle 37° with the horizontal. If the end touching the ground of the rod is being pulled by constant velocity v, then find
1. the velocity of the other end of the rod.
2.the angular velocity of the rod.
3. Are both of them constant?

71Make use of the fact that x2+y2= l2 , Now differentiate both sides and Put dx/dt = v as given.
Or In other way, You can use IAOR. Locate it by drawing perpendicular lines to the velocities of the ends of the rods. From there you can find w as well as vy
