Acerca do Movimento Uniforme, e as conversões temos que:
a) [tex]\boxed{\boxed{\sf \dfrac{10 \ m}{s} = \dfrac{36 \ km}{h}}}[/tex]
b) [tex]\boxed{\boxed{\sf \dfrac{108 \ km}{h} = \dfrac{30 \ m }{ s } }}[/tex]
Dados:
1 km = 1000 m
1 hora = 3600 s.
a)
[tex]\sf \dfrac{10 \ m}{1 s } =\dfrac{\dfrac{10}{1000} \ km }{\dfrac{1}{3600}\ h }\\\\\\\sf \dfrac{10 \ m}{1 s } =\dfrac{10}{1000} \ km } \cdot \dfrac{3600}{1 \ h} \ \\\\\\boxed{\boxed{\sf \dfrac{10 \ m}{s} = \dfrac{36 \ km}{h}}}[/tex]
b)
[tex]\sf \dfrac{108 \ km}{h} = \dfrac{108000 \ m }{3600 \ s } \\\\\\\boxed{\boxed{\sf \dfrac{108 \ km}{h} = \dfrac{30 \ m }{ s } }}[/tex]
