A pair of identical balls is connected by a massless rod, and thrown straight up into the air, such that the center of mass of the pair reaches a maximum height of 13.2 m above the point of release. 1.0 s after reaching this height, the velocity of one ball is measured to be 3.2 m/s upward. What is the velocity of the other ball at this time? Ignore air resistance.
A. 6.6 m/s down
B. 9.8 m/s up
C. 6.6 m/s up
D. 13.0 m/s down
E. 13.0 m/s up
F. 9.8 m/s down
D. 13.0 m/s down
