Answer 1

$\text{Time taken to reach the ground = 5s}</p><p>$

$\text{Height reached by the body in 5s = 5m}</p><p>$

$\text{Using the Formula}$

$\red{\boxed{h = \dfrac{1}{2} gt^{2},we\:get}}</p><p>$

$\pink{\boxed{5 = \dfrac{1}{2}g5^{2}}}</p><p>$

$\blue{\boxed{10 = 25g}}$

$\blue{\boxed{\dfrac{10}{25} = g}}$

$\blue{\boxed{0.4ms^{-2} = g}}$

$\mathfrak{Hence,\:the\:value\:of\:g\:will \:be\:o.4^{-2}}$
