Two children are riding on a merry-go-round. Child A sits at a greater distance from the axis of rotation than child B. Which child has the larger centripetal velocity?
A) A
B) B
C) They have the same non-zero centripetal velocity.
D) There is no way to determine without knowing the applied force.

I chose B, because it has a smaller distance from the axis of rotation. I'd assume that a greater distance would decrease the number. Did I think it through wrong?

there is nothing called centripetal velocity if there is then it is always zero in circular motion...

mos1635 · Answer

wich is centripetal velocity???|dw:1334741601487:dw|

anonymous · Answer

for linear velocity and centripetal acceleration,they are more for A

anonymous · Answer

Of course. I was trying to remember centripetal acceleration. But sadly one of my partners has my notes so I can't look over at those right away. Thank you so much!

anonymous · Answer

you are welcome!

mos1635 · Answer

a=v^2/r
a=(ω*r)^2/r
a=ω^2*r
r1>r2 =>a1>a2

P.S:omega (angular velocity) is same for both..and rest is as mos163 said..
