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)

FMotor = FReibung + FHangabtrieb + FBeschleunigung

$$ F_R=$$µ $$* F_G = 0,15 * (35000kg * 9,81\frac{N}{kg}) = 51502,5N = 51,5 kN$$

α = tan-1 * 0,1 = 5,71°

FH=FG * sin α =343350N * 0,099 = 33991,65N = 33,9 kN

FB=m * a =$$35000kg * 0,48\frac{m}{s^2} = 16800N = 16,8 kN$$

FMotor= 51,5kN + 33,9kN + 16,8kN = 102,2kN
