A 40 kg ladder is falling from rest. Assume, for
simplicity, that the ground and wall are frictionless
surfaces (but still exert normal forces!). Find the
angular acceleration of the ladder as well as the
normal force reactions at A and B at this instant.
The ladder has a length of 6 m and is currently at an
angle of 70° with the horizontal.
