Hello I´m a pupil of the gisela gym, munich I have mr Oswald as teacher in physics he forced me to write this i´m 16 years old and I love physics ^^

a)
x(t) = x0 + v * $\delta {t}$
Bussard:x(t) = 14 km + 95 $\frac {km}{h}$ * $\delta {t}$
Falke:x(t) = 0km + 153 $\frac {km}{h}$ * $\delta {t}$
Gleichgesetzt:14 km + 95 $\frac {km}{h}$ * $\delta {t}$ =$153 \frac {km}{h}$ * $\delta {t}$
$\delta {t}$ = 0,24 h
Gerundet:$\delta {t}$ = 14 min
Eingesetzt:x(t) = $153\frac {km}{h}$ * $0,24h$
x(t) = $36,72 km$ Gerundet:$x(t)=37 km$

2.9)
a)
t = $\frac {v}{a}$

t = 2,1 * 10-4

b)
x(t) = $\frac{1}{2}$ * a * t 2
t= $\frac {v}{a}$
x(t)=$\frac {1}{2}$ $\frac{v^2}{a}$
a= $\frac {v^2}{2*x(t)}$

a=3,6 *10 4 $\frac {m}{s^2}$

3.20 / 4.1

a)
v²=2ax

$\frac {v^2}{2x}$ = $\frac {192.90 \frac {m^2}{s^2}}{400m}$=0.48$\frac {m}{s^2}$

b) Fmotor=FHangabtrieb+FReibung+FBeschleunigung

FR = µ * FG = 0.15 * (35000Kg * 9.81 $\frac{N}{Kg}$) = 51.5 KN
α=tan -1=5.71°
FH=FG* sin α = 343350n * 0.099 =51.5kN
FB=$m * a = 35000kG * 0.48 \frac{m}{s^2}$= 102.2 kN
