Question

A merry-go-round is spinning at a rate of 4.0 revolutions per minute. cora is sitting 1.0 m from the center of the merry-go-round and cameron is sitting right on the edge, 2.0 m from the center. what is the relationship between the rotational speeds of the two children?

Answer 1

The rotational speed of the two children is the same. 
In fact, it is defined as
$\omega = \frac{\Delta \theta}{\Delta t}$
where $\Delta \theta$ is the angle covered in the time $\Delta t$. As it can be seen, this quantity does not depend on the distance from the centre, so the rotational speed is 4.0 revolutions per minute for both children.

Answer 2

Answer:

Same.

Explanation:

The rotational speed of an object is given by :

$\omega=\dfrac{\theta}{t}$

$\theta$ is the angular displacement

t is the time taken

The angular speed of a merry- go- round is 4 revolutions per minute. There are two persons Cora and Cameron. Cora is sitting 1.0 m from the center of the merry-go-round and Cameron is sitting right on the edge, 2.0 m from the center.

The rotational speeds of both of the children remains the same because it is independent of the distance from the center.
