Two children are riding on a merry-go-round. Child A is at a greater distance from the axis ofrotation than child B. Which child has the larger tangentialspeed?A. They hav e the same tangential speed. B.In order to find the tangential speed we need to know the masses. C.ch ild A. D.In order to find the tangential speed we need to know the radii. E.ch ild B.

C. Child A

Explanation:

It is obvious that object with greater radius will experience a greater tangential speed, because due to greater radius, it will be covering more distance in a unit time.

As it is stated that child A is at greater distance from axis of rotation, so his radius will be more, so he would be having more tangential velocity as compared to child B.  

Please note that, to calculate the tangential speed we must need the actual radii, but to guess which child would have more tangential speed, it is sufficient to know that one has a greater radius than other.

i would say the answer is food.

hope this !
