please need help with this hard physics problem?

a box rests on the back of a truck . The coefficient of ststic friction between box and truck bed is 0.300. When the truck accelerates forward what force accelerates the box. find the maximum acceleration the truck can have before the box slides

As long as the box doesn't slip, the frictinal force is equal to m*a and the friction is m*g*µk

the maximum a is
g*µk
or 9.81*0.300
