The initial velocity is 19 ft/s.
This equation is in the form
h(t) = -16t²+v₀t+h₀, where -16 is the gravitational constant, v₀ is the initial velocity, and h₀ is the initial height.
Our equation is h(t) = -16t²+19t+110. In this equation, the number in place of v₀ is 19, so the initial velocity is 19.
