Consider a uniform rod of mass 30 kg and length 1.7 m.  The rod is pinned at one end and allowed to hang vertically.  If the rod has zero gravitational potential in this position, how much gravitational potential energy does it have if it is rotated 44 degrees from the vertical, in J?  Use g = 10 m/s2. (Please answer to the fourth decimal place - i.e 14.3225)
