1. The problem statement, all variables and given/known data

A playground merry-go-round made in the shape of a solid disk, has a diameter of 2.64 m and a mass of 350.1 kg. Two children, each of mass 30.0 kg, sit on opposite sides at the edge of the platform. Approximate the children as point masses.


2. Relevant equations



3. The attempt at a solution

Only have a few minutes to turn this in

Approximate the children as point masses.

Is that the entire question? Did you leave out anything?

Well AFAIK, approximating the children as point masses, means that they can just be considered as point and the dimensions of the children don't matter. Not much can be done with the question if that is all the information given.
