hanecka A = 2 m/s²
t = 2 min = 2 *60 s = 120 s
Vo = 0
s = ?
s = a*t² /2
s = 2 m/s² * (120 s )²/2
s = 14400 m = 14,4 km
1 km = 1000 m

basetla $dane:\\v_{o} = 0\\a = 2\frac{m}{s^{2}}\\t = 2 \ min = 120 \ s\\szukane:\\s = ?$

$s = \frac{1}{2}at^{2}\\\\s = \frac{1}{2}*2\frac{m}{s^{2}}*(120s)^{2} \\\\s = 14 \ 400 \ m = 14,4 \ km$
