Two blocks, with masses mA and my, are connected to each other and to a central post by cords as shown in the figure(Figure 1). They rotate about the post at frequency f (revolutions per second) on a frictionless horizontal surface at distances r and pp from the postPart A Derive an algebraic expression for the tension in the segment of the cord between the post and block A (assumed massless). Express your answer in terms of the variables my. mg, TA, TD, f, and appropriate constants. 190 O 71 = AT f ( m, r, + m2(2 ) Submit Previous Answers Request Answer X Incorrect; Try Again; 3 attempts remaining Part B Derive an algebraic expression for the tension in the segment of the cord between block A and block B (assumed massless) Express your answer in terms of the variables my, mg, TA, 79. f, and appropriate constants.Item 11 Express your answer using two significant figures. A 28.0 kg block is connected to an empty 1,90 kg bucket by a cord running over a frictionless pulley The coefficient of static friction between the table meand = 12 kg and the block is 0/49 and the coefficient of kinetic friction between the table and the block is 0.34. Sand is gradually added to the bucket until the Previous Answers system just begins to move (Figure 1) Correct Figure
