Hello! :)
[tex]\large\boxed{19.6 m}[/tex]
Use the kinematic equation below to solve for the height of the building:
[tex]d = \frac{1}{2} at^{2}[/tex]
Where:
d = distance, or height of the building (m)
a = acceleration due to gravity (9.8 m/s²)
t = time (seconds)
Plug in the given values into the equation:
[tex]d = \frac{1}{2} (9.8)2^{2}\\\\d = \frac{1}{2} (39.2)\\\\d = 19.6 m[/tex]
