QUESTION:
Different materials, A, B, C, and D, rest on a table.
(a) Rank how much they resist being set into motion, from greatest to least.
(b) Rank the support (normal) forces the table exerts on them, from greatest to least.
Step 1 of 2
The resistance to being set into motion is primarily determined by two factors: mass and the coefficient of friction between the object and the table. Assuming the table is made of the same material across its length (and thus the coefficient of friction is constant for all objects), the material with the greatest mass would resist motion the most.
(a) From greatest to least, rank them by how much they resist being set into motion.
First, B = 15 kg iron A = 12 kg sand C = 10 kg water and D = 2 kg pillow
So the ranking from greatest to least resistance to being set into motion, assuming a constant coefficient of friction, would be BACD.
