A uniform ladder having mass 14kg and length 3m is released from rest when it is in the vertical position. If it is allowed to fall freely, determine the angle Theta at which the bottom end A starts to lift off the ground. For calculation assume the ladder is a slender rod and neglect friction at A.
The Attempt at a Solution
where I for end of rod = 1/3mL^2
I think we now need solve for the forces at point A, but I don't know how...
I also don't really understand at what point A would "lift"
Any help is appreciated!
