hi my name is hannah.i am a pupil from the gisela gymnasium in germany. my class is the 11n ,my physik teacher is herr osswald. peace!
I like to move it move it

 a) ges : Wsp 
    

D = F / s D = 50 N / 0,80 m D = 62,5 N / m

W_sp = 1 / 2 * D * s2

C)geg: m= 35t = 35000kg , t= 40s , v= 50 km/h = 13,8 m/s

ges:Wa

W_a = 0,5 * m * v2 W_a = 0,5 * (35000 kg) * (13,8 m/s)² W_a = 3375750 J = 3,4 MJ

d) geg: m= 3t = 35000 kg , t=40s , v = 50 km/h =13,8 m/s

 ges:P

P = W/t P = 3375750 J/40 s P = 84393,75 = 84,4 kW ( Arbeit ohne Reibung )

P = W_a * W_R /

lösung 1.6

x(t)=x₀ + v * ath>\Delta t</math>

x(t_f)=14km + 95 km/h * [math]\Delta t[/math]

x(t_b)=153km/h *[math] \Delta t[/math]

14km + 95km/h * [math]\Delta t[/math] = 153 km/h * [math]\Delta t[/math]

=> [math]\Delta t[/math] = 14 min

lösung 2.9

[math]x(t)=\frac {1}{2}* a* t^2[/math]
[math]t= /frac {v}{a}[/math]
[math]x(t)= /frac {1}{2}* a * (frac {v} {a}^2\ltbr\gt = /frac {v}^2 {2 *a* x(t)} = /frac (760 /frac {m}{s}{2* 0,8 s}[/math]
