2\,\text{kg}

block rests on a horizontal surface. The coefficients of friction between the block and the surface are

\mu_s = 0.40

and

\mu_k = 0.30

. A constant horizontal force of

9\,\text{N}

is applied to the block. (i) Will the block start sliding? (ii) If it does, calculate its acceleration.
