The maximum height is equal to 860.04m
Why?
We can find the maximum height of the object in two steps.
First step: Finding the initial speed.
Then,
Second step: Find the maximum height.
Now, again using the second equation, we need to subsitutite the obtained value for the initial speed into it, so:
Hence, we have that the maximum height is equal to 860.04 meters.
Have a nice day!
