A dart is thrown horizontally with an initial speed of 14 m/s toward point P, the bull's-eye on a dart board. It hits at point Q on the rim, vertically below P, 0.25 s later. Neglect air resistance.
(a) What is the distance PQ?
(b) How far away from the dart board is the dart released?
(b) How far away from the dart board is the dart released?
