3.20 Brummi Teil 1
a)
v² = 2ax

$\frac{v^2}{2x}= \frac{(13,89\frac{m}{s})^2}{2*200m}= \frac{192,90\frac{m^2}{s^2}}{400m}= 0,48\frac{m}{s^2}$

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

$F R =$ µ $* F_G = 0,15 * (35000kg * 9,81\frac{N}{kg}) = 51502,5N = 51,5 kN$
α = tan^-1 * 0,1 = 5,71°
F_H=F_G * sin α =343350N * 0,099 = 33991,65N = 33,9 kN
F_B=m * a = $35000kg * 0,48\frac{m}{s^2} = 16800N = 16,8 kN$
F_Motor= 51,5kN + 33,9kN + 16,8kN = 102,2kN
