## Question

###### 2 A dart is thrown horizontally with an initial speed of 10 m/s toward point P, the bull's-eye on a dart board. It hits at point Q on the rim, vertically below P, 0.2 s later. What is the distance PQ? How far away from the dart board is the dart released?Find the angle of elevation of a gun which fires a shell with muzzle velocity 366 m/s at a target on the same level but 4,575 m distant:
