Formula given: H=7+70t-16tsquared. Ball kicked straight up from a height of 7 feet. Ball travels 70 feet per second. How high is the ball after 3 seconds (t)?

  • algebra -

    Plug in 3.0 for t in your H vs. t equation. You should not have a problem doing that.

  • algebra -

    The equation you are given already takes into account the speed and direction that the ball was kicked, and the acceleration of gravity. All you have to do is substitute 3 for t and "turn the crank".
