SOCORRO GENTE Um ônibus desloca-se sobre uma trajetória retilínea segundo a função horária S = 10 + 30t (SI). a) Qual é a sua posição inicial? b) Qual é a velocidade escalar média do ônibus? (emojis pra chamar atenção)

Answer:

a) initial position = 10m

b) average velocity = 30m/s

Explanation:

The general equation of a motion with constant velocity is given by:

[tex]S(t)=S_o+vt[/tex] (1)

So: initial position

v: average velocity

t: time

You have the following equation:

[tex]S(t)=10+30t[/tex] (2)

If you compare the equations (1) and (2) you obtain that:

Answer:a) initial position = 10mb) average velocity = 30m/sExplanation:The general equation of a motion with constant velocity is given by:

[tex]S(t)=S_o+vt[/tex] (1)

So: initial position

v: average velocity

t: time

You have the following equation:

[tex]S(t)=10+30t[/tex] (2)

If you compare the equations (1) and (2) you obtain that:

[tex]S_o=10m\\\\v=30\frac{m}{s}[/tex]

hence:a) initial position = 10mb) average velocity = 30m/s
