Answer 2

Answer:

5.53 sec

Explanation:

Given

Height of building, s = 150 m

Initial Velocity of object, u = 0

Acceleration of object, a = g = 9.8 m/s²

Calculation

Equation of motion required

$s \: = ut \: + \frac{1}{2} a {t}^{2}$

Using the given values, we get

150 = 0*t + (1/2)*(9.8)t²

⇒ 150 = 4.9t²

⇒ t² = 150/4.9 = 1500/49

⇒ t = 10√15/7

t = 5.53 sec (approx)
