1. The problem statement, all variables and given/known data A boy with a mass of m1 is sitting in a carousel. The spinning frequency is 0.3355. The boy is also sitting on a weighing scale, will they show a number higher than m1g,lower or the same? (The mass of the weighing scale is 0). 2. Relevant equations mω2r=F ma=F ω2=4π2f2 3. The attempt at a solution I am trying to understand by which forces the weighing scale is affected and all I can think of is by the boy and by the normal force (and the centripetal force, but it doesn't matter here I think). Why they will show a value higher than m1g?
