so i should get the moment of inertia of the merry go round add it to the inertia of the two people and then divide the angular momentum by the inertia to get the magnitude of the angular velocity. okay.

exactly, i sent him an email complaining on how we can't even do the questions at home with all the resources, because they are too damn hard.

yea cody pretty much killed us this time

so why is he multiplying by 50. is it because of the number of tubes. I have the same question and i a little confused with the first one . i got my force to be 88.35N and if i multiply it by 50 i get 4417.5N. i don't know if I am correct.

so i should get the angular momentum of both the children separately and then add them together. but i don't know how i would go about doing that. with only the information given.

for the first question a) how did you calculate the area?

A merry-go-round consists of a flat circular disk mounted on a bearing at the center allowing it to freely rotate. Consider a mass-less merry-go-round with a 4 meter diameter. Initially a 30kg child sits at the east edge of the stationary merry-go-round. A second child with a mass of 40kg runs...
