FWHM = full with at half-maximum
RMS = root mean squared

Assuming 1 wavelength. Or if you can go in the reverse, I could figure it out backwards. Your help is much appreciated.

Two mass points of mass m1 and m2 are connected by a string passing through a hole in a smooth table so that m1 rests on the table surface and m2 hangs suspended. Assuming m2 moves only in a vertical line, what are the generalized coordinates for the system? Write the Lagrange equations for the system and, if possible, discuss the physical significance any of them might have. Reduce the problem to a single second-order differential equation and obtain a first integral of the equation. What is its physical significance? (Consider the motion only until m1 reaches the hole.)

You are standing on the ground. Does this mean there is no gravitational force acting on you? If there is such a force, why aren't you moving?

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 20.0 m/s. In the process, he moves his hand through a distance of 1.30 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.

I was wondering if kinetic energy is conserved during elastic collisions like when friction is not involved and neither is any other resistance. I was wondering if it was conserved if one object was standing still and the other hit it and also when both were moving at each other.

Hello!
Imagine that I'm now listening to a song on my computer and I happened to place my handphone just beside my speaker! Later on, the speaker made a strange cracking 'noise' and then, I got a call on my handphone!

Later on, my speakers made the same 'cracking noise' again and this time, I received a SMS!

I know this has something to do with the propagating waves and all that but could someone explain to me in detail on how the cracking noise interfers with the music played on the speaker? What phenomenon is this?

Thanx and take care! =)
