To find the tension in the wire produced by the bird, we can use the formula for gravitational force:
F = mg
Where:
F = Force (tension in the wire)
m = mass of the bird (1.44 kg)
g = acceleration due to gravity (9.8 m/s^2)
However, we need to find the net force that causes the wire to sag. The net force due to a sagging wire is equal to the gravitational force pulling the bird down.
Considering the wire sags by 0.139 m, we can use the formula for the force due to a sagging wire:
F = (1/2)mg
Now let's substitute the values into the formula to calculate the tension in the wire:
F = (1/2)(1.44 kg)(9.8 m/s^2)
F = 0.5(1.44 kg)(9.8 m/s^2)
F = 7.056 N
Therefore, the tension in the wire produced by the bird is approximately 7.056 N.
