$\text{Dane:}$

${\text{a}}_1=1\frac{\text{m}}{{\text{s}}^2}$

${\text{a}}_2=0\frac{\text{m}}{{\text{s}}^2}$

${\text{a}}_3=2\frac{\text{m}}{{\text{s}}^2}$

$\text{m}=2\text{kg}$

$\text{Szukane:}$

${\text{F}}_1\text{,}{\text{F}}_2\text{,}{\text{F}}_3=\text{?}$

Obliczamy siłę korzystając z drugiej zasady dynamiki:

${\text{F}}_1={\text{a}}_1\cdot \text{m}=1\frac{\text{m}}{{\text{s}}^2}\cdot 2\text{kg}=2\text{N}$

${\text{F}}_2={\text{a}}_2\cdot \text{m}=0\frac{\text{m}}{{\text{s}}^2}\cdot 2\text{kg}=0\text{N}$

${\text{F}}_3={\text{a}}_3\cdot \text{m}=2\frac{\text{m}}{{\text{s}}^2}\cdot 2\text{kg}=4\text{N}$
