Question

3:
Um carro retorna do km 102 ao km 65. Determine o deslocamento e as posições inicial e final.
AS = Sf - Si
a) As = 37 Km, Si = 65 Km, Sf = 102 Km
b) As = - 37 Km, Si = 65 Km, Sf = 102 Km
c) As = 37 Km, Si = 102 Km, Sf = 65 Km
d) As = - 37 Km, Si = 102 Km, Sf = 65 km
e) nenhuma das alternativas​

Answer 1

c) As = 37 Km, Si = 102 Km, Sf = 65 Km

Si = 102

Sf = 65

102-65

As = 37
