Question

A) 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.)

Golf ball, tennis ball, soccer ball, bowling ball, volley ball

B)As a physics demonstration, you want a special bowling ball made to demonstrate exactly 1 kg

Explanation / Answer

bowling ball > soccer ball > volley ball > golf ball > tennis ball

from given data we get density as aprox 1500kg/m3.

and radius as=5.369(cuberoot(M in kg)) cm

and i=2/5MRsqr

=>1=o.4*M*(0.05369)sqr*(M^2/3)

M=58 Kg approx
