Problem

A block on a horizontal surface experiences a limiting friction force of

6.0\,\text{N}

and, once sliding, a steady kinetic friction force of

5.0\,\text{N}

. If the normal reaction between the block and the surface is

20\,\text{N}

, calculate: (i) the coefficient of static friction, and (ii) the coefficient of kinetic friction.
