In the figure shown masses of the blocks A, B and C are 6kg, 2kg and 1kg respectively. Mass of the spring is negligibly small and its stiffness is 1000 N//m. The coefficient of friction between the block A snd the table is mu =0.8 . Initially block C is held such that spring is in relaxed position. The block is released from rest. Find (g=10 m//s^(2)) . (a) the maximum distance moved by the kinetic C . the acceleration of each block, when clongation in the spring is maximum.

In the figure shown, the system is released from rest with both the springs in unstretched positions. Mass of each block is 1 kg and force constant of each spring is 10 N/m. Maximum speed of the block placed horizontally is:
