Question

Um móvel percorre 500m em 10 segundos. Qual é a velocidade do móvel em K/h

(Cálculo)

Answer 1

Explicação:

x=500m

t=10s

v=?

v=x/t

v=500/10

v=50m/s

50.3,6km/h=180km/h

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \tt{ V_m=\dfrac{\Delta S}{\Delta t}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \tt{V_m=\dfrac{500}{10} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\tt{V_m=50\,m/s}} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \tt{ V_m=50\cdot3{,}6} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\tt{ V_m=180\,km/h}}} \end{gathered} }$
