A pair of identical balls are 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. Exactly 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
