A block A of mass 14 kg moves alongg an inclined plance that makes an angle of `30^(@)` with the horizontal . This block is connected to another block B of mass 14 kg by a taut massless string that runs around a massless frictionless pulley . The block B moves down with constant velocity . Calculate force of friction and coefficient of kinetic friction .
