Problem: A disk on the ground has a mass1 sitting on it at a distance of r1 from the center. It is rotating at a constant rate. The weight has a velocity v1. There is a string attached to mass 1 to mass 2 swinging beyond the disk at an angle (theta). Mass 2 is 1/5 the weight of mass 1 rotating at two times the distance and speed of mass 1. There is a coefficient of static friction between the two masses.
Part A: What is the smallest time of revolution mass 1 can have without flying off.
I want help to find the smallest time of revolution mass 1 can have without flying off.
