Any Help would be appreciated Problem 1: A person is to walk across a high wire strung horiziontally between 2 buildings 10.0 m apart. The sag when she is in the exact center of the rope is 10*. If her mass is 50.0kg what is the tension on the rope? Okay I know that the tension on the rope will be the same on each side as she is in the center of the rope. I also found the force of gravity to be 490N. but I am confused as too how I use this information to find the tension of the rope.
