Contact of surface?
And How does each affect the coefficient of Kinetic Friction?
Arrangement: Block on a horizontal table is pulled by the hanging mass in vertical position. Acceleration if measured by using the motion of the pulley. Rough and Smooth Surfaces with different surfaces area or small & large contact area are used.

Roughness of surface. Friction is mu. Friction is produced by rubbing objects together. Block moving on table produces friction.

The formulation is N=mg (typical reaction) u (mu) is the co-useful of friction between the block and the floor. So, the stress of friction performing could be uN i.e. umg The acceleartion could be F-uN= ma Fis the horizontal stress performing on the physique. So, what, you had no longer given the co-useful of friction. you need to use the above formulation to unravel the question.

the acceleration of the block is equal to the ratio of mass of the hanging block over the mass of the subtracted by the force of friction
the friction depends on the normal force, which in this case is equal to the force of gravity acting on the block on the table
