Answer :
The body's mass is 5 kg, and its acceleration is 5/sec2, hence F = 55 = 25 kg m/sec2 = 25 N.
Friction coefficient: why is it?
The amount of friction between two surfaces is measured by the coefficient of friction. You determine the resistance to motion at the intersection of two surfaces made of similar or different materials when you determine the coefficient of friction.
The materials being utilized have an impact on the coefficient of friction. For instance, rubber on pavement has a high coefficient of friction, which prevents the materials from sliding past one another as readily as ice on steel, which has a low coefficient of friction.
The former is also referred to as the dynamic or sliding friction coefficient in some instances.
