Answer 2

$\LARGE\bold{\underline{\color{teal}{ѕσlutíσn}}}$

$\;:;$

We know that :

$\large\bold{\mathtt{\boxed{\boxed{h=u t + {\frac{1}{2}} gt²}}}}$

Where ,

• h = height = ¿ (to find)

• u = initial velocity = 0m / s

• t = time taken to reach the ground = 2.5 secs

• g = Acceleration due to gravity = 9.8 m/s²

Using relation ,:

$\implies$ h = 0 × 2.5 + $\bold{\frac{1}{2}}$ gt²

$\implies$ h = 0 × 2.5 + $\bold{\frac{1}{2}}$ × 9.8 × (2.5)²

$\implies$ h = 0 + 4.9 × 6.25

$\implies$ h = 30.625 m

therefore ,

The height of building is 30.625 m.
