=4.6=

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

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

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

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
