A ball dropped from the top of a building takes 0.5 sec to clear the window of 4.9 m height. What is the height of building above the window?

A ball is dropped from the top of a building. The ball takes 0.5s to fall the 3m length of a window some distance from the to of the building. If the speed of the ball at the top and at the bottom of the window are v_(T) and v_(T) respectively, then (g=9.8m//s^(2))
