Wyjaśnienie:
t=10s
s=2m
Oblicz a
s=at²/2...................*2
at²=2s................/t²
a=2s/t²
a=4m/(10s)²
a=0,04m/s²
[tex]dane:\\v_{o} = 0\\t = 10 \ s\\s = 2 \ m\\szukane:\\a = ?\\\\Rozwiazanie\\\\Dla \ \ v_{o} = 0\\\\s = \frac{at^{2}}{2} \ \ /\cdot\frac{2}{t^{2}}\\\\a = \frac{2s}{t^{2}}\\\\a = \frac{2\cdot2 \ m}{(10 \ s)^{2}} \\\\a = 0,04\frac{m}{s^{2}}[/tex]
