Three children are riding on the edge of a merry - go - round that is a disk of mass 9 8 , radius 1 . 1 m , and is spinning at 1 5 p m . The children have masses of 2 3 . 2 , 2 8 . 4 , and 3 5 .
Randomized Variables
= 98
m1=23.2
m2=28.4
m3 = 35
=1.1m
=15pm
If the child who has a mass of 28.4 moves to the center of the merry - go - round, what is the new magnitude of angular velocity in rpm ?
