Elevator of torronto tower ?

    elevator of torronto tower......?

    the elevators in the torronto tower travels at 370m/min from ground level to the top floor . suppose that when the elevator begins to rise from ground level a coin is dropped from the top floor down the elevator shaft. at what height does the elevator meet the coin?


    give me a hint to how to start this question......
    i know that the distance traveeld by coin is given by 1/2*a*t^2
    but i cant seem think of any way to put it all together....

    Write down an expression for the height vs. time of the coin (you've already sort of done this).

    Write down an expression for the height vs. time of the elevator.

    When the two meet, their heights will be equal. Therefore, you should equate these two expressions and solve for the time, t, that satisfies this equation.
