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 = 0.50 kg, and the length of each half of the rod is L = 0.40 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 = 5.0 m/s.
Concepts:
(i) How many tension forces contribute to the centripetal force that acts on ball A?
(ii) How many tension forces contribute to the centripetal force that acts on ball B?
(iii) Is the speed of ball A the same as that of ball B? Calculations: Find the tension in each half of the rod.
