Question 423992:  A launched rocket has an altitude in meters, given by the polynomial h+vt-4.9^2, h is the height in meters v is the velocity in meters per second and t is the number of seconds for which it takes the rocket to become airborne. If the rocket is launched from the top of a tower that is 120 meters and the initial speed is 40 meters per second, what will its height be after 3 seconds??
 
the height will be __meters?

You can  put this solution on YOUR website!   A launched rocket has an altitude in meters, given by the polynomial  
h(t)= -4.9t^2 + vot + so, h is the height in meters vo is the velocity in meters per second, so is the initial height of the object and t is the number of seconds the rocket is airborne.  
If the rocket is launched from the top of a tower that is 120 meters and the initial speed is 40 meters per second, what will its height be after 3 seconds?? 
-------- 
h(3) = -4.9(3)^2+40(3) + 120 
----------------- 
h(3) = 195.9 meters
