can anyone please assist me with this question its hurting my head atm A steel ball is dropped from a building’s roof and passes a window, taking 0.125 s to fall from the top to the bottom of the window, a distance of 1.20 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.125 s. Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is 2.00 s. How tall is the building? im getting stuck with how it can pass the window when it bounces back up at the same velocity as free falling when gravity would be opposing it as it travels upwards?
