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 * t2

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
