a) $E_k = \frac {1}{2}* v^2$

$\frac {1}{2}*2000*(50/3.6) = 192901$

b) $E b = m * g * h = 1000 * 9,81 * 200 = 1962000 J$

c) $\frac{1}{2} 4000000* 1 = 2MJ$

Aufgabe 4.7

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