A plank having length L = 2 m and mass M = 3 kg is suspended from the ceiling by a wire that is attached a distance d = 0.5 m from its left end. The right end is initially held up so that the plank is horizontal, but is then released.
What is the magnitude of the acceleration of the center of mass of the plank just after the right end is released?
And can you explain why T is greater than mg?
