Задача №25.17
Условие
Стержень AB длины 4√2 м скользит концом A вниз вдоль оси y, а концом B вдоль оси x направо. Точка A движется по закону yA=(5-t2) м. Одновременно вдоль стержня от A к B соскальзывает точка M. Определить модуль абсолютной скорости и абсолютного ускорения точки M в момент t=1 с, если уравнение движения точки M вдоль оси s, совмещенной со стержнем, имеет вид s=AM=2√2t2 м.Решение
