The coefficients of static and kinetic friction between the body and the surface are 0.8 and 0.6 respectively. If the force continues to act even after the block has started moving, the acceleration of the block in ms^−2 is (g = 10 ms^−2 )

A horizontal force, just sufficient to move a body of mass 4kg lying on a rough horizontal surface is applied on it. The coefficients of static and kinetic friction between the body and the surface are 0.8 and 0.6 respectively. If the force continues to act even after the block has started moving, the acceleration of the block in ms^−2 is (g = 10 ms^−2 )

A horizontal force each of mass m. The system is released from rest. If accelerations of blocks A and B at any instant (not initially) are a1 and a2 Figure shows two blocks respectively then
