Abgabe 27.10.21       Frage: Gibt es noch eine größere Unverschämtheit?

Zur Sache:

a)

$a= 6m/s^2\\ \color{blue}s=\dfrac{a}{2}\cdot t^2$

${\color{blue}s_2}=\dfrac{6\ m\cdot 2^2\cdot sec^2}{2\cdot sec^2}=\color{blue}12\ m\\ {\color{blue}s_4}=\dfrac{6\ m\cdot 4^2\cdot sec^2}{2\cdot sec^2}=\color{blue}48\ m\\ {\color{blue}v=a\cdot t}=6\ m/sec^2\cdot4\ sec=\color{blue}24\ m/sec$

$s_6=s_4+v\cdot t=48\ m+24\ m/sec\cdot 2\ sec\\ \color{blue}s_6=96\ m$

b)

$\color{blue}v=at=\sqrt{2as}\\ {\color{blue}a=\dfrac{v^2}{2s}}=(\dfrac{65\cdot 10^3m}{h}\cdot\dfrac{h}{3600sec})^2\cdot\dfrac{1}{ 2\cdot30m}$

$a=5.433\ m/sec^2$

$t=\dfrac{v}{a}=\dfrac{65\ 000\ m\cdot sec^2}{h\cdot 5,433\ m}\cdot \dfrac{h}{3600\ sec}$

$t=3,323\ sec$
