Answer:
the answer is 352.8m
Explanation:
Since the gravitational constant is denoted as g
[tex]g = 9.8 \: \frac{m}{ {s}^{2} }[/tex]
and the ball needed 6 seconds to land, so we can calculate the height of the building as:
[tex]h = 9.8 \: \frac{m}{ {s}^{2} } \times {(6s)}^{2} = 9.8 \: \frac{m}{ {s}^{2} } \times 36 {s}^{2} = 352.8m[/tex]
