Problem

3.0\,\text{kg}

block is held against a vertical wall by a horizontal force of

50\,\text{N}

. The coefficients of friction between the block and the wall are

\mu_s = 0.50

and

\mu_k = 0.30

. a. (i) Will the block remain at rest or slide? Give a reason. b. (ii) If it slides, determine its acceleration and state the direction. Take

g = 9.8\,\text{m\,s}^{-2}
