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.
