Write a projectile height function from initial height and initial velocity
Problem
Write the height function for a ball thrown upward from \(5~\text{feet}\) at \(48~\mathrm{ft}/\mathrm{s}\). Start with \(h(t)=-16t^{2}+vt+h_{0}\), assign each given to its term with the correct sign, and verify \(h(0)\).
Big Picture
What this problem is really about
The projectile template assigns a distinct physical role to each term. We’ll keep gravity’s quadratic coefficient negative, use the upward initial velocity as the signed linear coefficient, place the launch height in the constant term, and evaluate time zero to verify the model’s starting condition and units.
