Q. A 2-kg aluminium block and a 6 kg copper block are connected by a light string over a frictionless pulley. They sit on a steel surface, where O= 30. When are rela=eased from rest will they start to move? If so resolve their acceleration and the tension in the string If not determine the sum of the magnitudes of the forces of friction acting on the blocks.
