Three blocks A,B and C are kept as shown in the figure. The coefficient of friction between A and B is 0.2, B and C I s0.1 C and ground is smooth. The mass of A,B and C are 3 kg , 2 kg and 1 kg respectively. A is given a horizontal velocity 10 m/s A,B and C always remains is contact i.e., lies as in figure. The total work done by friction during this process is 25xJ. Then find x.
