Частота высчитывается по формуле:

n=\frac{v}{2\pi R}

Ускорение высчитывается по формуле:

a_{c}=\frac{v^{2} }{R}

Выражаем скорость и подставляем в первую формулу:

n=\frac{\sqrt{a_{c}R} }{2\pi R}

Считаем, что ускорение равно 5g, по условию:

n=\frac{\sqrt{5gR} }{2\pi R}

Считаем, получаем ответ:

частота равна = 0.65 гц
