(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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?

2. Relevant equations

t = sqrt(2x/a) (Maybe?)

3. 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?
