    1. The problem statement, all variables and given/known data
    A stone is dropped from a height (h) and falls the last half of its distance in 4 seconds.
    (a) What is the total time of the fall?
    (b) From what height was the stone dropped?


    2. Relevant equations
    h=1/2(g)(T)²

    3. The attempt at a solution
    T=√2(T-4)

    One will need to set up two equations and most likely divide them to get rid of one of the variables and solve for the other.
