What is the instantaneous velocity of a thrown object at maximum height?

↳Redirected from "Suppose that I don't have a formula for #g(x)# but I know that #g(1) = 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

It depends!

Explanation:

If the motion is #only# vertical motion, then the velocity is zero.
If the motion is a #parabolic# motion, then the velocity is only the initial horizontal component of the velocity.
