As a 2.0-kg block travels around a 0.50-m radius circle it has anangular speed of 12 rad/s. The circle is parallel to the xy plane and is centered on the z axis, adistance of 0.75m from the origin. The z component of the angular momentum around the originis:
A. 6.0kg · m2/s
B. 9.0kg · m2/s
C. 11 kg · m2/s
D. 14 kg · m2/s
E. 20 kg · m2/s
