Problem
A 4.0 kg block rests on a horizontal table. You pull it with a spring scale and observe that the block does not move until the scale reads 18 N; once motion starts, the reading drops and stays constant at 14 N. Determine the coefficients of static and kinetic friction between the block and the table.
