Question

What is the magnitude of the acceleration caused by the force of kinetic friction acting on a box sliding across a level table? The coefficient of friction is 0.22

Answer 1

The kinetic friction formula is

`F=\mu mg`

Where mu = 0.22 and g = 9.8 m/s^2.

`\begin{gathered} F=0.22\cdot m\cdot9.8N \\ F=2.2mN \end{gathered}`

Therefore, the kinetic friction is 2.2m Newtons.
