    Rock hanging from ceiling swinging uniform circular motion

    Homework Statement A rock of mass 5.5kg is hanging from the ceiling moving in uniform circular motion. The radius of the orbit is .8m. The angle of the rope in comparison to if it were hanging straight down is 15 degrees outward. What is the magnitude of the force of the cord on the...
