Question 1166877
.
A toy rocket is shot vertically into the air from a launching pad 7 feet above the ground with an initial velocity 
of 150 feet per second. The height​ h, in​ feet, of the rocket above the ground at t seconds after launch is given by 
the function h(t)= -16t^2 +160t +7. How long will it take the rocket to reach its maximum​ height? What is the maximum​ height?

In your post, the definition of the function h(t) contradicts to the given data expressed in wording form.



Although I am enthusiastic in explaining such problems, I can not accept this assignment for execution due to this reason.
