Задача №44.25
Условие
Баллистический маятник, употребляющийся для определения скорости снаряда, состоит из цилиндра AB, подвешенного к горизонтальной оси O; цилиндр открыт с одного конца A и наполнен песком; снаряд, влетающий в цилиндр, производит вращение маятника вокруг оси O на некоторый угол. Дано: M — масса маятника; OC=h — расстояние от его центра масс C до оси O; ρ — радиус инерции относительно оси O; m — масса снаряда; OD=a — расстояние от линии действия ударного импульса до оси; α — угол отклонения маятника. Определить скорость снаряда, предполагая, что ось маятника O не испытывает удара, причем ah=ρ2.Решение
