A 1-kg mass is attached to the end of a light 1-m rod which is pivoted to rotate about the end opposite to the mass. The mass and rod are inverted and released from rest.
What is the tension in the rod when it is horizontal?
What is the magnitude and direction of the net force acting on the rod when it is horizontal?
