An object of mass M = 6.64kg is attached to a rope of negligible mass that is strung between two tops of two vertical poles. The horizontal distance between the poles is D = 3.14m, and the top right pole is a vertical distance h=0.451m higher than the top of the left pole. The object is attached to the rope at a horizontal position halfway between the two poles and at a vertical distance s = 1.092 m below the top of the left pole. Find the tension in each part of the rope due to the weight of the object.
