1. The problem statement, all variables and given/known data A 4.0kg magpie (bird) flies towards a very tight plastic wire on a clothes line. The wire is perfectly horizontal and is stretched between poles 4.0m apart. The magpie lands on the centre of the wire, depressing it by a vertical distance of 4.0cm. What is the magnitude of the tension in the wire? 2. Relevant equations W=mg trignometric functions W(x) = Wsin(theta) 3. The attempt at a solution This is off a textbook question, and their answer was 1000N. I got 0.8N ==' I had the following steps: - tan(θ) = 4/200 - θ = 1.15 degrees. - W(x) = mgsin(1.15) (where W(x) was the required component of weight, m = 4.0kg and g = 9.8ms^-2) - W(x) = 4.0kg x 9.8 x sin(1.15) = 0.8N What am i doing wrong? :( Any help is appreciated.
