### In a laboratory experiment on friction, a 136- block resting on a rough horizontal table is pulled by a horizontal wire. The pull gradually increases until the block begins to move and continues to increase thereafter. the figure shows a graph of the friction force on this block as a function of the pull.. . What would the graph look like if a 136 brick were placed on the box, and what would be the coefficients of friction be in that case?
