## How do you use quadratic equations in projectile motion?

The projectile-motion equation is s(t) = −½ gx2 + v0x + h0, where g is the constant of gravity, v0 is the initial velocity (that is, the velocity at time t = 0), and h0 is the initial height of the object (that is, the height at of the object at t = 0, the time of release).

## How do you solve quadratic projectile problems?

And feet now the equation that models the ball’s motion h of t equals negative 4t squared plus 12 t plus 5 is a quadratic equation. So the trajectory of the ball will be a parabola.

### How fast do you go skydiving?

120mph

The most common number you are likely to hear in relation to skydiving is 120mph. This is a useful number as it represents the average speed that people fall at when ‘belly to earth’ – the position you most likely to think of when you imagine somebody skydiving.

### How do you find the maximum height of a projectile quadratic function?
