I got it OH nevermind I got it.

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...

Ahh... thank you.

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...
