Question

os gráficos abaixo representam dois carros realizando movimento uniformemente variado. Calcule a aceleração em cada gráfico.​

Answer 1

$Dados\ Figura\ 1:\\ V0\longrightarrow 10 m/s \\V\longrightarrow 60 m/s\\ t\longrightarrow 10s \\\\ \framebox[3cm]{V-V0=Vm\\} \\ \\ \framebox[3cm]{60-10=50m/s} \\ \\\framebox{Vm=50m/s} \\\\\\Portanto:\\\\a=\frac{50}{10} \\\\\longrightarrow Reposta:5m/s^{2} \\----------\\\\Dados\ da\ Figura\ 2:\\V0\longrightarrow20 m/s\\V\ \longrightarrow 80 m/s\\t\ \ \longrightarrow 12 s\\\\\framebox[3cm]{V-V0=Vm\\}\\\\\framebox[3cm]{20-80= -60\\}\\\\Portanto:\\a=\frac{-60}{12}\\\\ \longrightarrow Reposta:-5m/s^{2}$
