#### Solution Preview

a.) Velocity will be according to largest arm (AB)

AB = r = 12 in = 12/12 ft

w = angular velocity =3 rad/s

ve = vd = vb = r*w = (12/12)*3 = 3 ft/s ...

#### Solution Summary

This solution provides a completed response, including the formulas and an outline of the metrics required, to calculate for the two unknown point values which pertain to this physics mechanics problem. All answers are provided in the correct units.
