Question

E um móvel se desloca 10 km a cada 20 segundos.qual a velocidade media em m/s? Faça o calculo

Answer 1

10kmx1000m=10.000m》x=10.000m/20s》x=500m/s

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \sf{10\,km\xrightarrow{\times1000}\,=10000\,m } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{V_m=\frac{\Delta S}{\Delta t} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{V_m=\frac{10000\,m}{20\,s} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\sf{V_m=500\,m/s} } \end{gathered} }$
