You can put this solution on YOUR website! given the polyonimal h+vt-4.9t^2, If a rocket launched from the top of tower 90 meters high with an intial upward speed of 30 meters per second, What will its height be after 2 seconds?
------
f(t) = -4.9t^2+30t + 90
---
f(2) = -4.9(2)^2 + 30*2 + 90
---
f(2) = 130.4 ft
