Homework Statement
Disk A, with a mass of 9.0 and a radius of 90 , rotates clockwise about a frictionless vertical axle at 30 . Disk B, also 9.0 but with a radius of 10 , rotates counterclockwise about that same axle, but at a greater height than disk A, at 30 . Disk B slides down the axle until it lands on top of disk A, after which they rotate together.
Homework Equations
ive been trying to find the acceleration? a=delta w/delta t but obviously this isn't wokring!
The Attempt at a Solution
I can't even attempt a solution. I am completely lost on this one, so much so i registered for physics forum just to get some help.
