Question

A ball dropped from the top of a building hits the ground 9 s later. How high is the building (in meters)

Answer 1

Answer:

1296 meters

Step-by-step explanation:

I assume we use the free fall equation $s=16t^2$

After 9 seconds:

$s=16t^2$

$s=16(9)^2$

$s=16(81)$

$s=1296$

This means that the height of the building is 1296 meters
