W czasie początkowym t0 = 0s ma prędkość 2m/s
W t1=1s ma 4m/s (2m/s+2m/s)
W t2=2s ma 6m/s (4m/s+2m/s)
W t3=3s ma 8m/s (6m/s+2m/s)
Ciało musi jechać 3 sekundy aby osiągnąć prędkość 8 m/s
V2 = 8 m/s
delta V = 8 m/s - 2 m/s = 6 m/s
a = 2 m/s^2
t = ?
a = delta V/t
a*t = delta V
t = delta V/a
t = 6 m/s / 2 m/s^2
t = 3 s
