F = ma

Where;

F is force

m is mass of the object dangling from the pulley

a is gravitational acceleration - 9.81

Accounting for friction, when the object is stationary subtract

F

Where;

F

μ

F

Once the object is moving/sliding...

This is wrong if things move. If the hanging mass (mThe net force acting on the object on the table is given by;

F = ma

Where;

F is force

m is mass of the object dangling from the pulley

a is gravitational acceleration - 9.81

A shortcut is to observe that the driving force is m
