[tex]m = 0,5 \ g = 0,0005 \ kg\\g = 10\frac{N}{kg}\\\\F_{g} =m\cdot g = 0,0005 \ kg\times 10\frac{N}{kg} =\boxed{ 0,005 \ N}[/tex]

[tex]m = 200 \ dag = \boxed{2 \ kg}[/tex]
3.
[tex]m = 0,1 \ kg\\h = 3 \ m\\g = 10\frac{N}{kg}\\\\E_{p} = mgh = 0,1 \ kg\times10\frac{N}{kg}\times 3 \ m = \boxed{3 \ J}[/tex]

[tex]14,4\frac{km}{h} = 14,4\times\frac{1000 \ m}{3600 \ s}= \boxed{4\frac{m}{s}}[/tex]
