A block of mass 2kg is lying on a floor. the coefficient of kinetic friction is 0.54. What will be the value of frictional force if the applied force is 28N and g=10m/s^2

Answer:
As fms = μsmg = 0.4 × 2 × 10 = 8 N.
The applied force of 2.8 N is less than fms (= 8 N) and as such the block does not move. When the block is at rest,
frictional force = applied force = 2.8 N
