Physics

Total mass (block plus masses)
0.1029 kg
0.1529 kg
0.2529 kg
0.302.9 kg
0.3529 kg
0.402.9 kg
Normal Force
1.01 N
1.50 N
2.48 N
2.97 N
3.46 N
3.95 N
f_smax
0.06 * 9.8 = 0.588 N
0.13 * 9.8= 1.27 N
0.225 * 9.8 = 2.21 N
0.305 * 9.8 = 2.99 N
0.31 * 9.8 = 3.04 N
0.38 * 9.8 = 3.72 N
Mass of hanger plus masses
0.06 kg
0.13 kg
0.225 kg
0.305 kg
0.31 kg
0.38 kg
From your measurements and analysis, and your understanding ofthe maximum static frictional force, can you come up with anequation that describes how f_smax depends on the normalforce? Hint: Is f_smax proportional to the normal force?Is f_smax proportional to the normal force squared?etc.
What is the proportionality constant? Â Â
What are its units?
Does the proportionality constant make sense in terms of thematerials of the block and horizontal surface? Explain.
