The largest Force appear when the maximal friction Force is required.
Second Newton law for the small block:



Second Newton law for the Big Block:



Answer:
In a time-position graph (s-t graph):
slope = velocity
In a time-velocity graph (v-t graph):
slope = acceleration
area under graph = change in displacement (distance travelled)
In a time-acceleration graph (a-t graph):
area under graph = change in velocity
