Задача №16.2
Условие
Колесо катится по наклонной плоскости, образующей угол 30° с горизонтом. Центр O колеса движется по закону xO=10t2 см, где x — ось, направленная параллельно наклонной плоскости. К центру O колеса подвешен стержень OA=36 см, качающийся вокруг горизонтальной оси O, перпендикулярной плоскости рисунка, по закону φ=(π/3)sin(πt/6) рад. Найти скорость конца A стержня AO в момент времени t=1 с.Решение
