I push a 16.5-kg box across a floor, which has a kinetic frictional force of Ff = 27.5 N. If my push of FA = 32 N gives it an acceleration of 0.35

 I push a 16.5-kg box across a floor, which has a kinetic frictional force of Ff = 27.5 N. If my push of FA = 32 N gives it an acceleration of 0.35 m/s2 , what is the coefficient of kinetic friction?

Equation(s) to use?

Final Solution?
