Question

um movél percorre uma distancia de 1.200 m em 4min. qual a sua velocidade escalar média ?

Answer 1

Resposta

4min = 240s
S = 1200m

V = S/t
V = 1200/240
V = 5m/s

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \sf{ 4\,min\xrightarrow{\times60}\,=240\,s} \end{gathered} }$

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ V_m=\frac{1200\,m}{240\,s}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{ V_m=5\,m/s}}} \end{gathered} }$
