Answer:
maximum height of the arrow will be 408 m
Step-by-step explanation:
We have given the function of height as 
We know that first derivative of height will be velocity
So first derivative of height


We know that at maximum height velocity will be zero

t = 5 sec
Sp arrow will be at maximum height at t = 5 sec
So height at t = 5 sec will be

So maximum height of the arrow will be 408 m
