Высота подъёма тела, брошенного вертикально вверх, вычисляется по формуле
h=V0t−(gt^2/2),
где V0 — начальная скорость движения в м/с, t — время движения в секундах, g≈10 м/с2. Скорость полёта в момент времени t вычисляется по формуле V=V0−gt.

Снежок подбросили вертикально вверх со скоростью 12 м/с. На какой высоте (в м) скорость полёта снежка будет в три раза меньше, чем в начале подъёма?
