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 100 meters and the initial speed is 60 meters per second, what will its height be after seconds rounded to the nearest tenth?

  • Algebra - ,

    I suggest you start by learning to spell the subject.

    Then take the time to type your equations correctly. It is much more likely to be
    h = ho + vo*t - 4.9 t^2. You left out t^2 term in any case.

    ho is the initial height, 100 m.
    vo is the initial speed, 60 m/s

    Finally, in your question:
    "what will its height be after ___ seconds rounded to the nearest tenth?"

    you failed to say how many seconds.
