Ugo [173]

Answer:

The rate of the train on level ground is 75 mph, and the rate of the train in the mountains is 30 mph like you mentioned. If you were asking for the time it takes for the train to travel 120 miles in that speed in the mountain, then it would be 4 hours.

Find the laplace transform of f(t)={0,(t−4),0≤t<4t≥4

Masja [62]

Presumably,

$f(t)=\begin{cases}0&\text{for }0\le t$

By definition of the Laplace transform,

$\mathscr L_s\{f(t)\}=\displaystyle\int_0^\infty f(t)e^{-st}\,\mathrm dt=\int_4^\infty(t-4)e^{-st}\,\mathrm dt$

Integrate by parts, taking

$u=t-4\implies\mathrm du=\mathrm dt$
$\mathrm dv=e^{-st}\,\mathrm dt\implies v=-\dfrac1se^{-st}$

so we get

$\displaystyle\mathscr L_s\{f(t)\}=\left(-\frac1se^{-st}(t-4)\right)\bigg|_{t=4}^{t\to\infty}+\frac1s\int_4^\infty e^{-st}\,\mathrm dt$
$=-\dfrac1{s^2}e^{-st}\bigg|_{t=4}^{t\to\infty}$
$=\dfrac{e^{-4s}}{s^2}$
