Question

part a rank the cups by the amount they depart from a straight - line path (most curved to least curved). rank from most curved to least curved. to rank items as equivalent, overlap them. reset help most least the correct ranking cannot be determined. submit request answer

Explanation:

Step1: Understand rolling - object behavior

The more the center - of - mass path is affected by the shape, the more curved the motion. A cylinder (A) rolls in a straight line as its cross - section is circular and symmetric. A frustum - shaped cup (B and C) will deviate from a straight line. The greater the difference in the radii of the top and bottom of the frustum, the more it will deviate.

Step2: Analyze the cups

Cup B has a more pronounced frustum shape (greater difference in top and bottom radii) compared to cup C. Cup A is a cylinder and will have the least deviation. So, cup B will deviate the most, followed by cup C, and then cup A.

Answer:

Most: B
Middle: C
Least: A
