Q1 of 57 Page 97

A body slipping on a rough horizontal plane moves with a deceleration of 4.0 m/s2. What is the coefficient of kinetic friction between the block and the plane?

The deceleration of body due to friction (a) = 4.0 m/s2

Mass of the body = m


Weight of the body= mg N


Frictional force (f)= ma


f= 4m N


Coefficient of kinetic friction =


so, μ= 0.4

A block is placed on a rough floor and a horizontal force F is applied on it. The force of friction f by the floor on the block is measured for different values of F and a graph is plotted between them.
