5.0\,\text{kg}

block slides on a horizontal surface with a coefficient of kinetic friction

\mu_k =0.20

. A horizontal force of

20\,\text{N}

acts to the right. Take

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

. Determine the block’s acceleration. a)

to the right b)

0\,\text{m\,s}^{-2}

2.0\,\text{m\,s}^{-2}

to the right d)

2.0\,\text{m\,s}^{-2}

to the left
