[tex]Dane:\\m = 800 \ kg\\F = 4 \ 000 \ N\\v_{o} = 0\\Szukane:\\v = ?\\\\Rozwiazanie\\\\\underline{v = a\cdot t}\\\\a = \frac{F}{m} = \frac{4000 \ N}{800 \ kg} = 5\frac{N}{kg} = 5\frac{m}{s^{2}}\\\\v = 5\frac{m}{s^{2}}\cdot10 \ s\\\\\boxed{v = 50\frac{m}{s}}[/tex]
Odp. Ten samochód uzyska prędkość v = 50 m/s.
