Hausaufgabe:

$x 1 (t) = 153 m k h - 1 * t$

$x 2 (t) = 14 k m + 95 k m h - 1 * t$

$153 k m h - 1 * t = 14 k m + 95 k m h - 1 * t$

$58 k m h - 1 * t = 14 k m$

$t = 0.24 h$

2.6 Anfahren

$a_{Zug} = 0.850 \frac {m}{s^2}$

$V_{Zug} = 75,0 \frac {km}{h}$

$V Z u g = a * t$

$t=\frac{v}{a}$ = $\frac{75\frac{km}{h}}{0,85\frac{m}{s}}24,5s$

4.6

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

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

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

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

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 $\frac {m}{s}$ =2MJ
