x(t)=x0 +vt

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

v=$\frac x t$

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

x1(t)=x2(t)

x1-x2=(v2-v1)t

t=$\$

x Ort
1) X(10s) = 4m/s x 10s X = 40m

2) X = 40m +(-2,0 m/s) x 10s X = 20m

3) X = 20m +(0 m/s) x 5s X = 20m

4) X = 20m +(1 m/s) x 5s X = 25m

5) X = 25m +(2 m/s) x 5s X = 35m

6) X = 35m +(4 m/s) x 10s X = 75m

7) X = 75m +(0 m/s) x 5s X = 75m

Schön, dass Sie an der Lösung dieser Aufgabe gearbeitet haben!--White Eagle 12:07, 22 October 2007 (CEST)

# Exercise 1.9: Reverse Gear

Calculate the ideal movement from the picture below of the t-x diagram,which we can imagine to continue as long as we want to.

a) vehicle speed
b) the coordinate x(1)of the position,which the vehicle has at the time t(1)=2min53s
c) the time t(2), on which it is at the position with the coordinate x(2)= -6,2km

It is essential: Start at 168m, x=0 after 12,5s
Horizontal axis: time in 2, Orthographic axis in m
