An object which is dropped from 100 feet above ground falls according to the formula s = -16t^2 + 100, where s is the distance from ground level at time t.

Which equation is equivalent to this formula?
S-100 = t^2

S-100 = t^2

s - 100 = t^2
-16 or

S-100+16= t^2

I choose the last selection but I'm not sure I'm correct

  1. a. (s-100)/(-16)=t²
    b. (s-100)/(16)=t²
    c. s/16 -100 = t²
    d. s-100+16=t²

    The last choice is definitely incorrect, here's why:
    s = -16t^2 + 100
    we need to express t² in terms of s.

    subtract 100 from each side to get:
    (s-100) = -16t²
    Divide by -16 on both sides to isolate t²:
    (s-100)÷16 = t²

    Now make your pick!

  2. Sorry that there was a typo, but it would have been easier to post a follow-up if the answer did not work out.

    "(s-100)÷(-16) = t²
    Now make your pick!"
