Aufgabenlösung für den 19.10.07

Lösung der Stegreifaufgabe Gruppe B:

x(t)1 = (x0 + v * [math]\Delta t[/math])/2
x(t)1 = (0 + 340[math]\frac{m}{s}[/math]*1s)/2
x(t)1 = 170m
x(t)2 = (x0 + v * [math]\Delta t[/math])/2
x(t)2 = (0 + 340[math]\frac{m}{s}[/math]*0.3s)/2
x(t)2 = 51m
v = [math]\frac{x1-x2}{\Delta t}[/math]
v = [math]\frac{170m-51m}{2.5s}[/math]
v = [math]47.6\frac{m}{s}[/math]
v = [math]171.36\frac{km}{h}[/math]

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
