Question

How can we calculate the height that an object is dropped

from ,if we only know the freely falling time?

any equations in physics?

Answer 1

If object is dropped so

initial velocity will be 0
acceleration will be g

$use \: this \: equation \: of \: motion \\ \\ s = ut + \frac{1}{2} g {t}^{2} \\ s = 0 + \frac{1}{2} g {t}^{2}$
put value of 't' only.
