Question 1127541
if a rocket is fired vertically into the air with a speed of 240 feet per second,it's height at time t seconds is given by h= -16t^2 + 240t. at the time will the rocket be 704 feet above the ground.
----------
That's not a rocket, it's a projectile.
Rockets have thrust and accelerate upward.
------------
h(t) = -16t^2 + 240t = 704
-16t^2 + 240t - 704 = 0
Solve for t.
