Homework Statement
Two uniform disks are connected by a light inextensible string supported by a massless pulley on a frictionless axis. (Very ideal LOL) The string is attached to a point on th circumference of disk A and wound around the disk B like a yo-yo.
Their moment of inertia does not equal 1/2mr^2 and the disks do not have uniform radial density.
For each disk A and B, the following are true:
I = .0254024 kgm^2
m = 1 kg
r = .2m
height = 1.6 m
g = 9.8 m/s^2
Which disk will reach the floor fit and what is the time interval for this disk to reach the floor?
Homework Equations
t = sqrt(2x/a) (Maybe?)
The Attempt at a Solution
As the spinning object would have a slower decent, object A would hit the ground first. (I think)
Past this, I'm totally lost. Anyone mind handing me a flashlight?
