Okay, here's the strategy: 1) We have to find angular velocity omega. 2) In order to do this, we need to analyze the force in each seat: dw:1349306339134:dw

which type of T is it. I'm used to using Tcos(theta) or Tsin(theta)

r is a little bit tricky here. It is the distance to center of rotation.

i am calculating it. r = 3.85 +

for part 2, does it only change the mass? and I plug in to find T?

sorry last bit haha forgot about it
