Question 21 [35 pts.) B 0.8 m As shown above, A 650-g tetherball A is connected to a fixed rod CB by the cord AB and is moving along a horizontal circular path at a constant speed v. You are required to: a. [5 Pts) Based on the following requirements, identify this kind of dynamic problem including the motion of the tetherball and your strategy for solution. (SO(1)-P11a] b. [5 Pts) Model the tetherball and formulate the kinetic relations of its motion (show the FBD and the KD). (SO(1)-P116) C. (S Pts] Define the acceleration of the ball as a function of the tension in the cord and 0, and show its direction. d. [10 Pts) Apply Newton's second law to determine the tension in the cord and the speed of the tetherball if 0 = 30°. (SO(1)-P11c e. [5 Pts) Define the relation between 0,V, and the tension in the cord, f. (5 Pts] Determine the minimum possible tension in the cord and the corresponding speed v
