Problem

During a trial a student measures a normal force of

5.0\,\text{N}

and a corresponding kinetic friction force of

1.9\,\text{N}

. A second measurement yields a normal force of

9.0\,\text{N}

with a kinetic friction force of

3.4\,\text{N}

. Assuming the relationship between friction force and normal force is linear, determine the coefficient of kinetic friction for the surface pair.
