Hi guys,

I'm Phil Stolz I live in Munich and I am 16 year old. I'm here at wikieducator in reason of my physic lessons, I hope you'll enjoy the time at our physic-materials-page ;) Physik is sexy!

## 2. Ebene

x(t)= x0+v*t

$\Delta x$=v*$\Delta t$

v=$\frac {x}{t}$

v=$\frac{ x_1 - x_0 }{\Delta t}$

# Aufgabenlösung für den 19.10.07

## Lösung der Stegreifaufgabe Gruppe B:

x(t)1 = (x0 + v * $\Delta t$)/2
x(t)1 = (0 + 340$\frac{m}{s}$*1s)/2
x(t)1 = 170m

x(t)2 = (x0 + v * $\Delta t$)/2
x(t)2 = (0 + 340$\frac{m}{s}$*0.3s)/2
x(t)2 = 51m

v = $\frac{x1-x2}{\Delta t}$
v = $\frac{170m-51m}{2.5s}$
v = $47.6\frac{m}{s}$
v = $171.36\frac{km}{h}$


Schön, dass Sie an der Lösung dieser Aufgabe gearbeitet haben! Stellen Sie die Lösung doch ein!--White Eagle 12:18, 22 October 2007 (CEST)

## Aufgabe 3.4

a)

D = F/S D = 50N/80cm D = 62.5 N/m

W = 0.5* D* s² W = 20J

b)

W = 0.5* D* s² W = 0.5* 62.5 * 1.3² W = 52,8 J

W(50)= W(130)-W(80) W(50)= 32,8J
