A rock thrown horizontally from the top of a radio tower lands 20.0 m from the base of the tower. If the speed at which the object was projected was 11.50 m/s, how high is the tower?

The leaning tower of Pisa is 55m high and 7m in diameter. The top of the tower
is displaced 4.5m from the vertical. Treat the tower as a uniform circular cylinder. (a)
What additional displacement measured from the top would bring the tower to the
verge of toppling? (b) What angle would the tower make with the vertical?
