Question

Um móvel parte do km 50, indo até
o km 60, onde, mudando o sentido do movimen-

to, vai até o km 32. O deslocamento escalar e a

distância efetivamente percorrida são ??​

Answer 1

$\large\boxed{\begin{array}{l}\sf O\, deslocamento\,escalar\, corresponde\,ao\\\sf espac_{\!\!,}o\, percorrido\,\Delta S,dado\,por:\\\sf\Delta S=\underbrace{\sf S_2}_{\sf posic_{\!\!,}\tilde{a}o\, final}-\underbrace{\sf S_1}_{\sf posic_{\!\!,}\tilde{a}o\, inicial}\\\sf\Delta S=32\,km-50\,km\\ \boxed{\sf\Delta S=-18\,km}\end{array}}$

$\large\boxed{\begin{array}{l}\sf A\,dist\hat ancia\, percorrida\,\acute e \,dada\,por:\\\sf\underbrace{\sf d_1 }_{\sf dist\hat a ncia\, inicial}+\underbrace{\sf d_2}_{\sf dist\hat a ncia\, final}\\\sf d=(60\,km-50\,km)+(60\,km-32\,km)\\\sf d=10\,km+28\,km\\\boxed{\sf d=38\,km}\end{array}}$
