12,87 sekon
Penjelasan:
Diketahui : h = 828 meter
Ditanya : t = ....?
[tex]\boxed{\displaystyle\tt~t = \sqrt{ \frac{2h}{g} } }[/tex]
[tex]\displaystyle\tt~t = \sqrt{ \frac{2(828)}{10 } } \\ \\ \displaystyle\tt~ = \sqrt{ \frac{1.656}{10} } \\ \\ \displaystyle\tt~ = \sqrt{165,6} \\ \\ \displaystyle\tt~ = 12,87~sekon[/tex]
