Flight route of a golf ball Wang Qiang is in a golf practice

Wang Qiang hit the ball somewhere during a golf practice. His flight path
There is only one intersection point between the parabola and the X axis at the apex of the parabola on the X axis, i.e. △ =0 b^2-4ac =4 (k+1) ^2-4*1*16=0 (k+1) ^2=16, k=3, or k=-5 (1) the maximum horizontal distance is the distance between the other intersection point of the parabola and the X axis and the origin, when y=0... Hit a ball from point O down the hill and fly to point a of the hole. The flight path of the ball is a parabola. If
^2+12, the solution shows that a= 4 / 27 of negative, and the analytical formula of the parabola is y= 4 / 27 of negative (X-9) ^2+12 and y= 4x^2+3 of negative 27; (3) ∵ when x=12, y=32/3 ≠ 4 root sign
Physics why golf balls fly farther than smooth balls of the same mass
Therefore, how to reduce the air resistance becomes the key. When golfers hit the ball, each ball gets a backward rotating force, which is closely related to these dents, as if a thick air pillow was formed under the ball. After a golf ball is played, it will fly at a high speed, and there will be a high-pressure area in front of itWang Qiang hit the ball somewhere in a golf practice, and the flight route of the ball was satisfactory
In a golf practice, Wang Qiang hit the ball somewhere, and its flight path met the parabola, where y (m) was the flight height of the ball, X (m) was the horizontal distance of the ball flying out, and the result was that the horizontal distance from the ball to the hole was 2mFive factors affecting the flight path of golf
According to the law of conservation of momentum, in the formula m1v1=m2v, M1 and M2 are constant before and after hitting the ball. Therefore, the velocity of the club head is proportional to the initial velocity of the ball. That is to say, the greater the speed of the club head, the farther the ball will be hit. Among the above five elements, (3), (4), (5) determine the distance, (1) and (2) determine the flight route and landing point... Hit a ball from point O down the hill and fly to point a of the hole. The flight path of the ball is a parabola, such as
^2 +12 solution, the analytical formula of a = -4/27 parabola is y = -4/27 (X-9) ^ 2 +12 br /> ③ Analysis of parabola of formula substituted in a (12,4 √ 3)Determination of golf flight direction
There are only two factors that affect the flight direction of golf: the swing trajectory. The swing trajectory is actually the trajectory of the club head touching the ball. The swing trajectory determines the initial direction of the ball flight. It has three possibilities: follow the target line, to the left of the target line, and to the right of the target line. Rod face angle... A ball flies to point a of the hole. The flight path of the ball is a parabola. If not considered
427, so the analytical formula of the parabola is: y=-427 (x? 9) 2+12. (3) from (1) we know that the coordinates of point C are (12, 0), and it is easy to get AC = 43, then we can get that the coordinates of point a are (12, 43). When x=12, y =? 427(12?9)2+12＝323≠4
About golf parabola
Y=-1/40 (x-20) 2+10 the maximum distance is 40 and the maximum height is 10 (20-10 √ 2) or (20+10 √ 2)
... Hit a ball and fly to point a of the hole. The flight path of the ball is part of the parabola
So ac=4 √ 3, co=12, that is, the coordinate of point a is (12, 4 √ 3), and these three points are substituted into y=ax&\178+ Bx+c, the analytical expression of the parabola can be obtained. A not necessarily on this parabola. The general analytic formula of the parabola is y=ax&\178+ bx+c。
