Answer:
h = 110.24 m
Step-by-step explanation:
It is given that,
A rock is thrown up from the ground at a velocity of 84 feet per second. The formula
gives the rock's height in feet after t second.
We need to find the maximum height of the rock. For maximum height put 
So,

Put t = 2.62 s in the equation of height. So,

So, the maximum height of the rock is 110.24 m.
