Question 723485
If a rocket is launched with an initial velocity of 1600 feet per second, when will the rocket be 14,400 feet high?  Use the formula h = vt - 16t^2 to solve the problem.
--------------
 h = vt - 16t^2 = 14400
1600t - 16t^2 = 14400
solve for t.
-----------------
Why is that called a rocket?  It's a projectile.
Rockets have thrust and accelerate after launch.
