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
