Two blocks A and B of equal masses are released from an inclined plane of inclination `45^(@)` at t = 0. Both the blocks are initially at rest. The coefficient of kinetic friction between the block A and the inclined plane is 0.2 while is 0.3 for block B. Initially the block A is `sqrt2m` behind the block B. At what time in seconds will their front faces come in a line, (Take `g=10ms^(-2)`)
