Problem

A crate of mass

5\,\text{kg}

is pulled along a horizontal floor by a constant horizontal force of

40\,\text{N}

. The coefficient of kinetic friction between the crate and the floor is

0.20

. Starting from rest, determine the speed of the crate after it has been pulled through

3.0\,\text{m}

. (Take

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