1. The problem statement, all variables and given/known data A mass of 20kg is hanging on a rope. Another cord is tied to the rope part way down and is attached to a wall. This causes the rope to make a 60 degree angle to the ceiling. a) Calculate the tension force in the upper section of the rope. b) Calculate the force exerted by the cord on the wall. 2. Relevant equations Tension=SinX * F 3. The attempt at a solution I believe part a) is (where gravity = 9.8): Tension = Sin60 * (20 * 9.8) Tension = 170N (2sf) I'm not sure what to do for part b), hence why I've posted this.
