A ball is dropped from the top of a building. The ball takes 0.5sec to fall past the 3m height of a window some distance from the top of the building. If the speed of the ball at the top and the bottom is $V_{T}$ and $V_{B}$ , the establish a relationship between vb and vt take (g = 9.8m/s).

A steel ball is dropped from a building's roof and passes a window of lenght $10 m$ , taking $1 s$ to fall from the top of the window to the bottom of the window. It then falls onto a sidewalk and bounces back past the window, moving from bottom to top in $1 s$ . Assume that the upward flight is an exact reverse of the fall. The time the ball spends below the bottom of the window is $2 s$ . How tall is the building?
