$\text{Dane:}$  

$\text{v}=100\frac{\text{km}}{\text{h}}=100\cdot \frac{1000\text{m}}{3600\text{s}}=27,8\frac{\text{m}}{\text{s}}$  

${\text{t}}_1=8,89\text{s}$  

${\text{t}}_2=7,41\text{s}$  

${\text{t}}_3=6,35\text{s}$  

${\text{t}}_4=5,55\text{s}$  

 

${\text{t}}_5=4,94\text{s}$  

$\text{Szukane:}$  

${\text{a}}_1\text{,}{\text{a}}_2\text{,}{\text{a}}_3\text{,}{\text{a}}_4\text{,}{\text{a}}_5=\text{?}$  

Obliczamy przyspieszenie z definicji:

$\text{a}=\frac{\text{v}}{\text{t}}$  

Podstawiamy kolejno dane:

${\text{a}}_1=\frac{\text{v}}{{\text{t}}_1}=\frac{27,78\frac{\text{m}}{\text{s}}}{8,89\text{s}}=3,12\frac{\text{m}}{{\text{s}}^2}$   

${\text{a}}_2=\frac{\text{v}}{{\text{t}}_2}=\frac{27,78\frac{\text{m}}{\text{s}}}{7,41\text{s}}=3,75\frac{\text{m}}{{\text{s}}^2}$   

${\text{a}}_3=\frac{\text{v}}{{\text{t}}_3}=\frac{27,78\frac{\text{m}}{\text{s}}}{6,35\text{s}}=4,37\frac{\text{m}}{{\text{s}}^2}$    

${\text{a}}_4=\frac{\text{v}}{{\text{t}}_4}=\frac{27,78\frac{\text{m}}{\text{s}}}{5,55\text{s}}=5,0\frac{\text{m}}{{\text{s}}^2}$     

${\text{a}}_5=\frac{\text{v}}{{\text{t}}_5}=\frac{27,78\frac{\text{m}}{\text{s}}}{4,94\text{s}}=5,62\frac{\text{m}}{{\text{s}}^2}$  

Teraz uzupełniamy tabelke:

L.p.	Wartość siły wypadkowej [N]	Czas przyspieszania samochodu od 0 do 100 km/h [s]	Wartość przyspieszenia [m/s2]
1	2500	8,89	3,12
2	3000	7,41	3,75
3	3500	6,35	4,37
4	4000	5,55	5,0
5	4500	4,94	5,62
