A uniform ladder of mass m = 40 kg and length [ = 10 m is leaned against a frictionless wall. A person with mass M = 80kg stands on the ladder at a distance = 7 m from the bottom, as measured along the ladder. The ladder makes a 30 degree angle with the floor. The floor is not frictionless and the ladder does not move. What is the normal force that the wall exerts on the ladder? Image size: s m L Max Please enter a numerical answer below.
