Apply quadratic functions to physical situations such as projectile motion under gravity.
Identify the initial height from a projectile function
Problem
Identify the initial height in projectile function \(h(t)=-16t^2+48t+5\).
Big Picture
What this problem is really about
Initial height means the model’s output at the launch instant, so the decisive input is zero. We’ll substitute that input, observe which terms vanish, and distinguish the remaining position value from coefficients that describe velocity and gravity.
