4.0\,\text{kg}

crate on a horizontal surface is pulled toward the right by a rope exerting a constant

22\,\text{N}

force. Kinetic friction between the crate and the surface exerts a

16\,\text{N}

force opposite the motion. What is the magnitude of the crate’s acceleration? (a)

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

(b)

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

(c)

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

(d)

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