Question 9 of 9 - /10 3 Ball A is attached to one end of a rigid massless rod, while an identical ball B is attached to the center of the rod, as shown in the figure. Each ball has a mass of m = 0.410 kg, and the length of each half of the rod is L - 0.470 m. This arrangement is held by the empty end and is whirled around in a horizontal circle at a constant rate, so that each ball is in uniform circular motion. Ball A travels at a constant speed of VA = 4.30 m/s. Find (a) the tension of the part between A and B of the rod and (b) the tension of the part between B and the empty end. (a) 2L (b) B (c) (a) Number Units (b) Number i Units
