A ball is dropped from a building's roof. It passes a window of height $h_w$, taking time $t_w$ to fall from top to bottom. It then falls to a sidewalk, bounces, and returns past the window. The total time the ball spends below the bottom of the window is $T$. Assume the upward flight is a perfect reversal of the downward flight.
In terms of $h_w$, $t_w$, $T$, and $g$, what is the total height $H$ of the building?
