Question

Um bloco de 5 kg tem uma força de 20 n qual a sua aceleração​

Answer 1

a = F/m = 20/5 = 4 m/s² <=====©

Answer 2

2ªlei de Newton

$\textcolor{goldenrod}{\vec{Fr}=m.\vec{a}}$

$\textcolor{goldenrod}{\vec{Fr}=m.\vec{a}}$

$\textcolor{goldenrod}{20=5.\vec{a}}$

$\textcolor{goldenrod}{\vec{a}=\frac{20}{5}}$

$\textcolor{orangered}{\vec{a}=4m/{s}^{2}}$
