5\,\text{kg}

crate rests on a horizontal floor. The coefficient of kinetic friction between the crate and the floor is

0.20

. A worker pulls the crate horizontally with a steady force of

30\,\text{N}

toward the east. Taking

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

, calculate the magnitude of the crate’s acceleration. (a)

6.0\,\text{m/s}^2

(b)

3.1\,\text{m/s}^2

(c)

4.0\,\text{m/s}^2

(d)

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