Kirun is leaning a ladder (mass m = 15 kg and length L = 5.0 m) against the side of his house. An ice storm has just passed, so both the ground and the side of the house are frictionless. Kirun realizes that the ladder will not remain propped up in these conditions, so he connects a support rope horizontally between the bottom of the lad- der and the side of his house. Kirun allows the bottom of the ladder to slide outward until the rope tightens up and the ladder remains steady. Now the ladder makes an angle of 0 65 with the horizontal and the support rope is com- pletely horizontal. What is the tension T in the support rope? The symbolic answer must be written in terms of the variables m, L, T, 0, and g, though not all of these vari- ables may be needed. (Hint: there are two normal forces acting on the ladder, one from the ground and one from the side of the house.) = Kirun is leaning a ladder (mass m = 15 kg and length L = 5.0 m) against the side of his house.
