where is the initial upwards velocity and is the initial launching height. If I am understanding your question, this is what you are looking for. So the height AT the time of launch was 60 meters.
The height of the object at the time of the launch is
Step-by-step explanation:
We know that the height in meters, x seconds after the launch is modeled by the following function :
For example, after from the launch the height of the object is :
If we want to know the height of the object at the time of the launch we will need to find the height of the object at because that is the instant where the object is launched.
If we use in ⇒
We find that the height of the object at the time of launch is
