Answer:
The height of the building is 153.664 meter.
Step-by-step explanation:
Consider the provided function.

Here t represents the time v₀ represents the initial velocity, s₀ represents the initial height and s(t) represents the height after t seconds.
It is given that the splash is seen 5.6 seconds after the stone is dropped.
That means after 5.6 seconds height s(t) = 0, Also the initial velocity of the stone is 0.
Substitute respective values in the above function.



As height can't be a negative number so the value of s₀ is 153.664.
Hence, the height of the building is 153.664 meter.
