1) Um corpo de massa igual a 60 kg move-se com aceleração de módulo igual a 5 m/s
Qual o módulo da força resultante que atua no corpo?​

Answer 1

use a segunda lei de Newton , multiplica a massa pela aceleração para calcular a força resultante

Fr = m . a

Fr = 60 . 5

Fr = 300 N ✓

Answer 2

$\Large\displaystyle\begin{gathered} \bf\blue{F\acute ormula:}\end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{ F_R=m\cdot a}}} \end{gathered} }$

$\Large\displaystyle\begin{gathered} \bf\blue{ Dados:}\end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \sf{ \begin{cases}\sf F_R=?\,N\\\sf m=60\,kg\\\sf a=5\,m/s^2\end{cases}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \bf\blue{Soluc_{\!\!,}\tilde ao:}\end{gathered} }$

$\Large\displaystyle\begin{gathered} \sf{F_R=60\cdot5 } \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \therefore\red{\underline{\boxed{\boxed{\sf{F_R=300\,N }}}}}~~(\checkmark) \end{gathered} }$
