Спортсмен двигаеться с постоянной по модулю скоростью,пробегая по стадиону n=3,5 круга.Во сколько раз отличаются модуль перемещения дельта r и путь s спортсмена за время движения???

Автор ответа: Просветитель

Спортсмен совершил 3 круга + полкруга. Значит, перемещение равно диаметру круга r=2*R. Пройденный путь равен $S = 3,5*2* pi *R$
Отношение равно $frac{S}{r} = frac{3,5*2* pi *R}{2*R} = 3,5* pi$
