Pomocy ! Ze wzoru s=Vo*t+1/2at^2 Wyznacz a) Vo b)a

[latex]a)\s = v_{o}t + frac{1}2at^2}}\\v_{o}t = s - frac{1}{2}at^{2}} |*2\\2v_{o}t = 2s - at^{2} /:2t\\v_{o} = frac{2s-at^{2}}{2t}\\lub\\v_{o} = frac{s}{t}-frac{at}{2}[/latex] [latex]b)\s = v_{o}t + frac{1}{2}at^{2}}\\frac{1}{2}at^{2}} = s - v_{o}t |*2\\at^{2} = 2(s-v_{o}t) /:t^{2}\\a = frac{2(s-v_{o}t)}{t^{2}}[/latex]
