Homework Statement



The coefficients of static and kinetic friction between a 59 kg box and a horizontal surface are 0.66 and 0.37, respectively.

(a) What is the acceleration of the object if a 330 N horizontal force is applied to the box?

(b) What is the acceleration if the applied force is 485 N

Homework Equations



F=ma, coefficent of friction equations

The Attempt at a Solution



I tried using the equations

but I am not really sure how they are supposed to be used

Is this applied to the box at rest? in that case the applied force has to be greater than the max Static Friction for the box to have any acceleration.
