Question 1038304
A model rocket is launched straight upward with an initial velocity of 22m/s. The height of the rocket (h) in meteres, can be modelled by h(t)=5t^2+22t, where t is the elapsed time in seconds. What is the maximum height the rocket reaches? 
=============
h(t)=5t^2+22t
-------
h(t) increases monotonically with time.
There's no max.
