1. The problem statement, all variables and given/known data

Assume ## \psi(x, 0) = e^{-\lambda |x|} \: for \: -\infty < x < +\infty ##. Calculate ## \phi(k_x) ## and show that the widths of ## \phi, \psi ##, reasonably defined, satisfy ##\Delta x \Delta...

## x'=\gamma (x-vt) \\ t'=\gamma (t-vx) ##

In the limit ## v \ll 1 ##, we have ## \gamma \approx 1+\frac 1 2 v^2 ##, so we have, in this limit:

## x' \approx (1+\frac 1 2 v^2)(x-vt)=x-vt+\frac 1 2 v^2 x-\frac 1 2...

My hobby is to design algorithms especially data compression algorithms, but when I cant find a solution to my problems I usually go find myself a different problem to solve because it helps me think differently or maybe it lights a bulb about the original problem …today I stumbled on...

When the brick with mass 3 kg is hanged in a spring, it is lengthened 25 cm. If we lengthen the spring with 15 cm more and leave it free how may times does the brick take to come back to the equilibrium position

Why the time is the quarter of a period?]]>

Calculate the length of time it would take for an object to fall 10.0m if g were one sixth the value of earth's g.

g=1/6(-9.8)= -1.633333333 m/s^2

a=-1.633333333m/s^2
