Lösning 3.1:1
FörberedandeFysik
a) \displaystyle v=v_0+at=10m/s+3 m/s^2\cdot 6s= 28m/s
b) \displaystyle OA: \displaystyle v^2=v_0^2+2a\cdot s \rightarrow (10(m/s)^2=0+2(4m/s^2)\cdot OA(m) \Rightarrow OA=12,5 m
\displaystyle AB: \displaystyle s=v+\frac{1}{2}\cdot at^2 \Rightarrow AB=(10m/s)\cdot (6s)+\frac{1}{2}(3m/s^2)(6s)^2= 114 m
\displaystyle OB=OA+AB=126,5m
