Apply quadratic functions to physical situations such as projectile motion under gravity.
Identify the initial velocity in a projectile function
Problem
Identify the initial velocity in projectile function \(h(t)=-16t^2+48t+5\).
Big Picture
What this problem is really about
In a standard projectile model, each coefficient has a physical role rather than merely being a number to compute with. We’ll match the linear time coefficient to initial vertical velocity, interpret its sign as direction, and preserve rate units in the conclusion.
