**4) A uniform rod (M = 2.0 kg, L = 2.0
m) is held vertical about a pivot at point P, a ****distance
L/4 from one end (as in the Figure). The rotational inertia of the rod ****about
P is 1.17 kg*m**2. If it starts rotating from rest, what is the linear speed
of ****the lowest point of the rod as it passes again through the
vertical position (v)?
