Привет, я смог на половину решить эту задачу..
Я составил уравнение, но не смог полноценно до конца его решить, т.к. у нас 2 искомых значение (масса пули и скорость ее после столкновения).
Я нашел какой импульс должен от этих двух искомых получаться (2,114) и подобрал комбинацию в екселе (м2=2,114/v2) таким образом, чтобы потом до и после реакции сумма импульсов равнялась. На фото моё решение.
ответ к задаче: масса пули(заряда) 0,035 кг., а в2 60,44 м/с (на фото я упустил что в скобках не 4*4,1 , а 4-4,1; потом пересчитал)
Если что пиши.. или кто знает как до этого числа дойти не методом подбора объясните)
