A ball is dropped from a height of 100 meters. How long will it take to hit the ground? Show work

Respuesta :

20.4081/s^2

Explanation:

ignoring air resistance and with the knowledge that the acceleration of gravity is 9.8 we can use that to find the answer.

The formula is (hX2)/(9.8m/s^2)

so

100mX2 = 200m

200m/9.8m/s^2 = 20.4081/s^2
