a) [math] E_k = \frac {1}{2}* v^2 [/math]

[math]\frac {1}{2}*2000*(50/3.6) = 192901[/math]

b) [math] E_b = m*g*h= 1000*9,81*200 = 1962000J [/math]

c) [math]\frac{1}{2} 4000000* 1 = 2MJ[/math]

Aufgabe 4.7

a) E=[math]\frac {1}{2}[/math]mv2
-->[math]\frac {1}{2}[/math][math]*[/math]2000kg[math]*[/math]50[math]\frac {km}{h}[/math]=193kJ
b) E=mgh
-->1000kg[math]*[/math]9.61[math]\frac {n}{kg}[/math]*200m=1,96MJ
c) E=[math]\frac {1}{2}[/math]mv2
-->[math]\frac {1}{2}[/math][math]*[/math]4000t[math]*[/math]1[math]\frac {m}{s}[/math]="MJ
