A row of six 1.0 N wooden blocks is being pushed across a tabletop at a constant speed by a toy tractor that exerts a force of 1.3 N on the row. What is the coefficient of kinetic friction between the wooden blocks and the tabletop?

F = ma = μmg

The local acceleration of gravity is g = 9.8 m/s²
The mass of each block is 1.0 N / g

Plug in 1.3 N for F, the mass, and g and solve for the coefficient of kinetic friction μ.
