a) ges: Fahrzeuggeschwindigkeit
Δx = 0 - 168 m = - 168m
Δt = 12,5 sekunden
= v
v = - 13,44m/s = -48,3km/h
b) t = 2 min 53 sek
168m + ( -13,4m/s ) 173s
= - 2,16km
Schön, dass Sie an der Lösung dieser Aufgabe gearbeitet haben!--White Eagle 12:11, 22 October 2007 (CEST)
c) t =
übersetzung:
it follows in this case:
a=
(movement with constant aceleration from that rests)
if the venture owns already at the beginning of the movement a beginning speed v0 so the functional equation is
v(t) = v0 + at
the graph is origin-straight a postponed:
(1) Δt
(2) Δv
(3) v0
(4) t0
It turns out for a>0 a movement with consistently
acceleration, for a<0 a movement with consistently speed and for a=0 a movement with consistently delay ( falling graph)
!Attention! This time the formula a =
is wrong!!
To be used is:
a is also the gradient of the line.
Definition:The acceleration a is the gradient of the t-v-line.
The unit of the acceleration is m/s².

A testinstitution analyses the movement of a vehicle.The results are:
a) Draw a t-v-diagramm! (10s=1 cm, 1m/s=1 cm)
b) Name the type of movement in the particular timezones!
c) Find out the accelerations by using the graph!

F(gewicht) = F(zentral)
m w2 r = m g /:m
w 2 = r g
w 2 = g : r
w 2 = 9,81 N/Kg : 1,0m
w = 9,81
w = 3,13
v = w r
v = 3,13 * 1m
v = 3,13 m/s
