1. The problem statement, all variables and given/known data The coefficient of static friction between block A and a horizontal floor is 0.45 and the coefficient of static friction between block B and the floor is 0.30. The mass of each block is 2.0 kg and they are connected together by a cord. What is the tension in the cord connecting the two blocks at this instant? Answer: N 2. Relevant equations and 3. The attempt at a solution as the friction force on the block A is 8.82 N, for just to move it the force is 8.82 N and this is applied by the cord only. Hence the tension in the cord is 8.82 N T = 0.45 * 9.8 * 2 = 8.82 N => INCORRECT. Why??? Please help!
