Môt khẩu súng phóng lựu được đặt ở chân một con đê cao. Đích lựu đạn cần phóng
trúng nằm cách đó 620 mét và ở độ cao 50 mét. Vận tốc (tốc độ) của quả lựu đạn
khi ra khỏi nòng súng phóng lựu đạt 91m/s, sức cản của không khí có thể bỏ qua.
Vậy phải chỉnh góc phóng α ban đầu của súng ở độ lớn là bao nhiêu so với phương
nằm ngang?
