In addition to the question at the bottom, I need help with calculating the normal force.

Table 3. Peak Static Frictional Force Total Mass {kg} Trial 1 (N) Trial 2 {N} Trial 3 {N} Average (N) Total Mass {kg} Trial 1 (N) Trial 2 {N} Trial 3 {N} Average {N} Table 6.

When the data for applied force vs normal force is plotted, the slope of the graph is equal to the coefcient of friction. Plot graphs of average force vs normal force from the data in Table 5 and Table 6
