他这球的滞空时间太夸张(这球的滞空时间太离谱了)

Considering the response to a Chinese comment
I see the user mentioned, "他这球的滞空时间太夸张," which translates to "The hang time of his shot is too insane." This seems like sports commentary, although there's no question asked. I might respond by clarifying: are they referring to basketball, football, or volleyball?
It could be interesting to explain "hang time," including some physics formulas and examples from famous athletes. I’ll also guide them on how to estimate it from videos. I'll need to keep things concise, following the instructions.Finalizing the response
I don’t need to run any extra steps here; I’ll just provide a final response. It might be helpful to offer options like estimating hang time based on a clip and comparing it to typical values.
I can also provide a quick formula: for basketball shots, typical hang time is around 0.9-1.3 seconds. I could break down how to approximate hang time using the formula and even give a realistic example. It’s important to mention the impact of camera angles and frame rates in measuring hang time.Providing measurement methods
I don’t think providing a code snippet is necessary right now. Instead, I can suggest a method for measuring hang time using a smartphone. The user could display the timeline frame by frame in the video or use a free tool for analysis. Since we’re in a CLI context, I can offer to do a computation if they share the frame rate and frame count. I’ll keep my final answer short and concise, and I’ll make sure to respond in Chinese.
听着像在看神仙球!你指的是篮球/足球/排球哪种球?不同项目的“滞空时间”差别很大。
快速参考
- 篮球投篮:常见约 0.9–1.3 s;彩虹三分可到 ~1.4–1.6 s(再长就很罕见)
- 足球高球/解围:~2–3 s;守门员开大脚或高抛可更久
- 橄榄球开球/弃踢:4.5–5.5 s(顶级水平)
- 棒球高飞球:5–7 s 也常见
物理上怎么估
- 同高度出手与落点时,飞行时间 T = 2 v0 sinθ / g
- 只知道最高点相对出手高度 h 时:T ≈ 2√(2h/g)。例:h=3 m → T≈1.56 s
可能“看起来更久”的原因
- 慢放/高帧率视频;镜头跟拍球路;出手点与落点高度差;强背旋让轨迹更“飘”

要不要我帮你算精确滞空?
- 给我视频帧率(fps)和从出手到落地/入网的帧数,我能算出 T 并和同项目的典型值对比。
- 或把片段发我,我也可以帮你估(标出出手帧与落地/触球帧即可)。
