with solutions please

Answer 1

$10 \: m$

Explanation:

$Given,\: \: \: t = 2s , \: \: u = 0 \: m {s}^{ - 1} \\ Let, \: \: distance = s \\ we \: \: know \: \: \boxed{s = ut + \frac{1}{2}g {t}^{2} } \\ then, \: \: \: s = 0 \: m {s}^{ - 1} \times 2s + \frac{1}{2} \times 10 \: m {s}^{ - 2} \times {2s}^{2} \\ = 0 + 10 \: m \\ = 10 \: m$
