Blocks A and B, of masses 2 kg and 3 kg respectively, are connected by a light inextensible string on a horizontal floor. The coefficients of friction for A and B are 0.2 and 0.1 respectively. A horizontal force of 20 N is applied to B away from A. The blocks move together. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.
Find the acceleration of the blocks.
Find the tension in the string.
