Problem
Consider a homogeneous rod of constant cross-section and length l attached to a freely rotating joint at one end. At the beginning, the rod points straight up and is in a homogeneous gravitational field with acceleration g. Due to a slight whiff of wind, the rod starts turning and "falling" down, but is still held on the joint. Find the acceleration of the end of the rod in time.
