A ball is dropped from the top of a building that is 784 feet high. The height of the ball above ground level is given by the polynomial function h(t)= -16t to the second power + vot + ho where t is measured in seconds, vo is the initial velocity and ho is the initial height.
What is the formula after all the known values are put in?
How high is the ball after 3 seconds?
How far has the ball traveled in 3 seconds?
When will the ball hit the ground?

  • Algebra -

    h(t) = -16t^2 + 784
    because v0 = 0

    Now just plug in your numbers as needed. If you get stuck, show how far you got, and we can help out.
