Mathematical and Physical Analysis of the Shooting Techniques of High-pole Throwing Hydrangea 

By using the methods of literature and mathematical analysis, the present representative technical theory of high-pole throwing Hydrangea is analyzed, this paper analyzed the technical movements of the high-pole throwing Hydrangea of technology, such as the angle, speed and height of release of the athletes, as well as the running track data of the parabolic arc top height, the range of passing circle and the place of falling of the high-pole throwing Hydrangea champion in the 12th Guangxi Student Games in 2019. The results show that: the range of the angle of release is 64 0 ≤ α ≤72 0 ; when the angle of release is 64 0 lower limit, the velocity of release is v 0 ≥13.04m/s lower limit, when the ball reaches the highest point, it passes through the lower edge of the circle. When the angle of release is 72 0 upper limit, the velocity of release isv 0 ≥13.17m/s, the top of the arc of the ball is 1.8m away from the top of the circle, and it passes through the lower edge of the circle when it falls; when the angle of release is 66 0 , the velocity of release is v 0 ≤13.70m/s upper limit and the ball passes through the upper edge of the circle when it rises to the highest point; under the three circumstances, the arc top of the ball does not exceed the circle, and the height from the ground does not exceed 10m. At the same time, it proves the scientificity and reliability of the projection technique of Hydrangea.
