The coefficients of static and kinetic friction between a 445 N crate and the warehouse floor are 0.565 and 0.450, respectively. A worker gradually increases his horizontal push against this crate until it just begins to move and from then on maintains that same maximum push.
What is the acceleration of a crate after it has just started to move?
The Attempt at a Solution
I tried to multiply the kinectic friction coefficient by the Normal Force to get kinetic friction. Then I tried to divide Kinectic Friction by the mass of the box and I got:
4.39 m/s2 but it was wrong.
