Megan rides a horse at the outer edge of a merry-go-round. She is located 6 m from the central axis and is a bit frightened of the speed. So her parents place her on a horse 3 m from the axis. While on the inner horse, how will her linear speed compare with her speed on the outer horse?

u know
circumference of a circle=2πr
OpenStudy (shamim):
here r is the distance frm the axis to the horse
OpenStudy (shamim):
valu of r is greatet circumference of circle will b greater

so... it would be
inner horse: 37.70
outer horse: 18.85
OpenStudy (shamim):
value of r is smaller, then circumference will b smaller
OpenStudy (shamim):
I did not understand 37.70
OpenStudy (shaleiah):
37.699
OpenStudy (shamim):
from where number comes

in ur question no number is occuring
OpenStudy (shaleiah):
the question asks: While on the inner horse, how will her linear speed compare with her speed on the outer horse.
OpenStudy (shamim):
yes
OpenStudy (shamim):
inner horse has less r
OpenStudy (shamim):
so inner horse has less circumference

Alright, so I can put.... Megan's linear speed on the outer edge of a merry-go round will be greater than her speed on the inner horse.
