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. Each ballhas a mass of m= 0.50 kg, and the length of each half rodis L= 0.1m. This arrangement is attached by the empty end,C, to a pole on a frictionless horizontal surface and is whirledaround in a horizontal circle at a constant rate. Ball A travels ata constant speed of 2.0 m/s.
a) Draw a sketch of the situation. Clearly indicate the paths of the balls.
b) What is the relationship between the speeds of ball A and ball B?
c) How many tension forces act on ball A? How many tension forces act on ball B? Draw a free body diagram for each of the balls clearly label all of the forces.
d) Calculate the tension in each half of the rod.
