I know that the moment of inertia of a disk about the axis perpendicular to the plane of the disk is
I=1/2 MR^2
and by the perpendicular axis theorem the moment of inertia about the other axis is
I=1/4 MR^2
I want to get the 2nd result with calculus. I can't get the right answer...
Homework Statement
Well I've pretty much boiled the problem down to this:
Let a = 1.767+0.3213t
v(0)=0
x(0)=0
then I got
x(t)=(0.8835+0.05355 t) t^2
Given x=6.1
Solving for t I got t=2.45175
But I'm just curious. If I calculate average acceleration I get a_av=2.16.
If I...
Homework Statement
I am given the object distance and height, and the focal length of the mirror and I must draw the ray diagram.
Although this was drawn by a computer program that I programmed, I thought it would be more relevant in this forum, because I believe that the rays are correctly...
