Question

How can quadratic equations be used to model ballistics?

Answer 1

The height `H` of a projectile above the ground after `t` seconds is given by the formula `H_t = -1/2*g*t^2 + V_0*t + H_0`,
where `g` is a physical constant (gravitational acceleration `~~9.8 m/s^2`), `V_o` is the initial velocity and `H_0` is the initial height.

We notice that this is a quadratic equation of variable `t`.
