Homework Statement Find the solution for: ({\partial{}_t}^2 -D \Delta^2)G(\vec{r},t;\vec{r}_o,t_o)=\delta(\vec{r}-\vec{r}_o)\delta(t-t_o) In two dimensions. Homework EquationsThe Attempt at a Solution Am I supposed to use bessel eqs? I'm kind of stuck in starting the problem :L

Yes :DD

In two weeks I have my clasical mechanics exam. This includes rigid solid and non inertial frame of reference chapters. Do you know any problem that involves both themes? This is how my exam is going to be :nb) Also, do you have any solved-problems book you could recommend me? Thanks in...

Now, the second part of the problem is solving it by using the center of mass of the system disk+point mass. I have a doubt when computing the Inertia Moment of my new system. The system's center of mass position is: \begin{cases} x_{cm}=x_{0} - d\sin{\varphi}=R\varphi - d\sin{\varphi}\\...

You're right, I have thought about it and seems totally logic.

First of all thanks a lot for helping me with this problem. I have already corrected that typo :) You mean K_{p}=\frac{1}{2} m({\dot{x}^2}_{p}+{\dot{y}^2}_{p} ) with no additional rotating-motion terms right? I feel so foolish about considering the distance with respect to the center of the...

Homework Statement In a uniform gravitational field, there is a uniform solid disk of of mass M and radius R. A point mass m is glued to the disk at a point that is at a distance a from the center of the disk. The disk rolls without slipping. Find the frequency of small oscillations about the...

Hello everybody, this is Lisa. I am currently studying the 2nd year of the physics degree. Nice to meet you all :p
