Problem

5\,\text{kg}

block on a horizontal surface is pulled by a constant horizontal force of

12\,\text{N}

. The coefficient of kinetic friction between the block and the surface is

0.20

. Take

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

. The magnitude of the block’s acceleration is a)

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

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

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

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