Comparing conserved quantities

The four objects in the figures below are moving as indicated by the arrows. A curved arrow indicates a rotation about the center. For object (A) use the coordinates shown. For the others, take the origin at the center of the circle. Use the directions associated with the coordinate axes shown at the right. Construct a table with the values of

at the instant shown for each case. Express your answers in terms of m, v, and R. (Include an indicator of the direction where appropriate.) Which system has the largest and smallest of each of the quantities? Explain your reasoning.
