The function is:
h%28t%29+=+-4.9t%5E2%2Bh%5B0%5D which allows you to calculate the height (in meters) of of an object dropped from an initial height of h%5B0%5D as a function of time (t in secods).
When the object (pebble) reaches the ground, h = 0, so substitute this and t = 3 into the equation and solve for the corresponding value of h%5B0%5D.
0+=+-4.9%283%29%5E2%2Bh%5B0%5D
h%5B0%5D+=+44.1 meters.
