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 * [math]\delta {t}[/math]
Bussard:x(t) = 14 km + 95 [math]\frac {km}{h}[/math] * [math]\delta {t}[/math]
Falke:x(t) = 0km + 153 [math]\frac {km}{h}[/math] * [math]\delta {t}[/math]
Gleichgesetzt:14 km + 95 [math]\frac {km}{h}[/math] * [math]\delta {t}[/math] =[math]153 \frac {km}{h}[/math] * [math]\delta {t}[/math]
[math]\delta {t}[/math] = 0,24 h
Gerundet:[math]\delta {t}[/math] = 14 min
Eingesetzt:x(t) = [math]153\frac {km}{h}[/math] * [math]0,24h[/math]
x(t) = [math]36,72 km[/math] Gerundet:[math]x(t)=37 km[/math]

2.9)
a)
t = [math]\frac {v}{a}[/math]

t = 2,1 * 10^-4


b)
x(t) = [math]\frac{1}{2}[/math] * a * t ²
t= [math]\frac {v}{a}[/math]
x(t)=[math]\frac {1}{2}[/math] [math]\frac{v^2}{a} [/math]
a= [math] \frac {v^2}{2*x(t)}[/math]

a=3,6 *10 ⁴ [math]\frac {m}{s^2}[/math]

3.20 / 4.1

a)
v²=2ax

[math]\frac {v^2}{2x}[/math] = [math]\frac {192.90 \frac {m^2}{s^2}}{400m}[/math]=0.48[math]\frac {m}{s^2}[/math]



b) F_motor=F_Hangabtrieb+F_Reibung+F_{Beschleunigung}

F_R = µ * F_G = 0.15 * (35000Kg * 9.81 [math]\frac{N}{Kg}[/math]) = 51.5 KN
α=tan ^-1=5.71°
F_H=F_G* sin α = 343350n * 0.099 =51.5kN
F_B=[math]m * a = 35000kG * 0.48 \frac{m}{s^2}[/math]= 102.2 kN
