Question

de acordo com a imagem determine a aceleração
v=70m/s_______________________ v°=50m/s
200s

Answer 1

$\large\boxed{\begin{array}{l}\tt dados\begin{cases}\sf v_0=50~m/s\\\sf v=70~m/s\\\sf t_0=0\\\sf t=200~s\\\sf a=?\end{cases}\\\underline{\rm soluc_{\!\!,}\tilde ao:}\\\sf a=\dfrac{v-v_0}{t-t_0}\\\\\sf a=\dfrac{70-50}{200-0}\\\\\sf a=\dfrac{20}{200}\\\\\sf a=0,1~m/s^2\end{array}}$
