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?

@Amenah8

OpenStudy (shamim):

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

OpenStudy (shaleiah):

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

OpenStudy (shamim):

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

OpenStudy (shamim):

so inner horse has less speed

OpenStudy (shaleiah):

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.

OpenStudy (shamim):

right!"!!

OpenStudy (shaleiah):

thank you !

OpenStudy (shamim):

u r most welcome!!
