Условие
Угловая скорость тела ω=7 рад/с, мгновенная ось его составляет в данный момент с неподвижными координатными осями острые углы α, β и γ. Найти величину скорости v и проекции ее vx, vy, vz на координатные оси для точки тела, координаты которой, выраженные в метрах, в данный момент равны 0, 2, 0, а также расстояние d этой точки от мгновенной оси, если cosα=2/7, cosγ=6/7.Решение
