Question: A 6.0- kg concrete block rests on a level table. A 3.9- kg mass is attached to the block by a string passing over a light, frictionless pulley. If the acceleration of the block is measured to be 1.4 m/s2,
Part A: What is the coefficient of friction between the block and the table?
I need help to find the coefficient of friction between the block and the table.
