Answer 2

Answer:

$g = 0.3ms {}^{ - 2}$

Explanation:

height of the object above ground, h =15m

time taken to reach ground, t = 10s

value of the, g = ?

We know that

$h = ut + \frac{1}{2} g {t}^{2}$

$= > 15 = 0 \times 15 + \frac{1}{2} \times g \times {10}^{2}$

$= > 15 = 0 + \frac{1}{2} \times g \times 100$

$= > 15 = 50g$

$= > g = \frac{15}{50}$

$= > g = \frac{3}{10}$

$\: so \: = 0.3ms {}^{ - 2}$
