Using quadratic function concepts, it is found that:
- It takes 1 second to reach maximum height.
- The maximum height is of 25 yards.
- It takes approximately 3.2 seconds for the rocket to hit the ground.
The height of the rocket <u>after x seconds</u> is given by:
Which is a quadratic function with coefficients .
The maximum height will be a reached at a time of , and will be of , considering the vertex given by:
Then:
Thus:
- It takes 1 second to reach maximum height.
- The maximum height is of 25 yards.
It hits the ground when , thus:
We want the positive root, so, it takes approximately 3.2 seconds for the rocket to hit the ground.
