Three children are riding on the edge of a merry-go-round that is 105 kg, has a 1.70-m radius, and is spinning at 16.0 rpm. the children have masses of 22.0, 28.0, and 33.0 kg. if the child who has a mass of 28.0 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm? ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as points.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
