Gravity on Jupiter
If a rock falls from a height of 20 meters on planet Jupiter, its height H (in meters) after x seconds is approximately:
H(x) = 20 - 13x^2
(a) When is the height of the rock 15 meters?
(b) When does the rock strike the ground?
NOTE: The question comes from my precalculus book. Chapter title: FUNCTIONS.
I totally get it.
So, I needed to REPlACE H(x) with 15 meters for a and 0 for part b to simplify.
It never strikes the ground, Jupiter does not have a surface (as we understand it,

Actually there is some indication that there may either be a diamond core (which seems a bit far-fetched, but possible) or a solid metallic hydrogen core (which I personally think is more likely.) But agreed, we can obviously only speculate at this point.
