PROBLEM: A block of metal of mass 2 kg on a horizontal table is attached to a mass of 0.45 kg by a light string passing over a frictionless pulley at the edge of the table. The block is subjected to a horizontal force by allowing the 0.45 kg mass to fall. The coefficient of sliding friction between the block and table is 0.2.

Calculate: A) the initial acceleration; B) the tension in the string; and C) the distance the block would continue to move if, after 2s of motion, the string should break.
