Problem

A block of mass

2\,\text{kg}

lies on a horizontal table. The coefficient of static friction between the block and the table is

\mu_s=0.4

. A horizontal force of

5\,\text N

is applied to the block. Take

g=10\,\text{m\,s}^{-2}

. (a) Will the block start moving? (b) What is the magnitude of the frictional force acting on the block?
