Na figura a seguir, as duas sequências de pontos indicam as posi-
ções, ao longo do plano da figura, ocupadas pelos móveis MeN
em instantes intervalados de 0,10s. M e N movimentam-se
somente da esquerda para a direita.
Para o
móvel M
Para o
móvel N
Sabe-se que cada quadradinho, na figura, tem lado representando
uma distância de 1,0cm e que os movimentos de MeN são
uniformes.
Admita que
(1) a primeira foto corresponda à origem dos tempos (t = 0);
(2) a origem dos espaços corresponda à posição do móvel M na
quinta foto e do móvel N na sétima foto;
(3) as trajetórias estejam orientadas da esquerda para a direita.
Pedem-se
a) as velocidades escalares dos móveis Me N.
b) as equações horárias dos espaços para os móveis Me N.
