In a laboratory experiment on friction, a 139-N 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 (Figure 1) shows a graph of the friction force on this block as a function of the pull.

Question
Transcribed Image Text:In a laboratory experiment on friction, a 139-N 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 (Figure 1) shows a graph of the
friction force on this block as a function of the pull.
Part C
What would the graph look like if a 139 N brick were placed on the block, and what would be the coefficients of friction be in
that case?
