Question
Map sapling learning It is generally a good idea to gain an understanding of the "size" of units. Either using an Internet search, or referring to the hint panel below, find the official size and masses of the sports balls listed below and calculate their moments of inertia about their center of mass. Rounding your results to the nearest power of 10, categorize each of the sports balls according to the order of magnitude of the moment of inertia. (Note that some of the balls are hollow.) sane o' the bais ar magitude of the moment of imertia.

The bowling alls most familiar to your students has a weight of 16.0 pounds and have a circumference of 25.9 inches, but do not have a moment-of-inertia equal to 1 kg- m2 Since the sporting goods manufacturer has no understanding of how "big 1 kg m2 is, calculate the diameter of the demo bowling ball (in inches) it will need to manufacture. Assume that bowling balls are solid, with a constant density. Number inExplanation / Answer
here,
weight of the ball , w = 16 pounds
let the radius of demo ball be r
circumference , C = 2 * pi*r
25.9 = 2*pi*r
r = 4.12 inch
the diameter of the demo ball , d = 2*r
d = 8.25 inch
the diameter of the demo bowling ball is 8.25 m
