A person with mass m = 60 kg is located on a fixed platform with mass M = 100 kg. With what frequency will the platform rotate if a person starts moving in a circle with a radius of r = 5 m around the axis of rotation of the platform? The speed of human movement relative to the platform is 4 m/s. Platform radius R = 10 m. Consider the platform as a disk, and the person as a point mass.
