Answer:
c Four stories below the top.
Explanation:
t = Time taken
u = Initial velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow s_1=0\times t+\dfrac{1}{2}\times g\times 1^2\\\Rightarrow s_1=0.5g\ m[/tex]
In two seconds
[tex]s_2=0\times t+\dfrac{1}{2}\times g\times 2^2\\\Rightarrow s_2=4\times 0.5g\\\Rightarrow s_2=4s_1[/tex]
So, in two seconds the water balloon will fall 4 stories below the top
