Answer:
455165.278 m
Explanation:
P = Power = 3.7 W
v = Velocity = 10.7 m/s
Amount of fat = 4 g
1 gram of fat provides about 9.40 (food) Calories
Energy given by 4 g of fat
![E=4\times 9.4\times 4186\\\Rightarrow E=157393.6\ J](https://tex.z-dn.net/?f=E%3D4%5Ctimes%209.4%5Ctimes%204186%5C%5C%5CRightarrow%20E%3D157393.6%5C%20J)
Time required to burn the fat
![t=\dfrac{E}{P}\\\Rightarrow t=\dfrac{157393.6}{3.7}\\\Rightarrow t=42538.811\ s](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7BE%7D%7BP%7D%5C%5C%5CRightarrow%20t%3D%5Cdfrac%7B157393.6%7D%7B3.7%7D%5C%5C%5CRightarrow%20t%3D42538.811%5C%20s)
Distance traveled by the bird
![s=vt\\\Rightarrow s=10.7\times 42538.811\\\Rightarrow s=455165.2777\ m](https://tex.z-dn.net/?f=s%3Dvt%5C%5C%5CRightarrow%20s%3D10.7%5Ctimes%2042538.811%5C%5C%5CRightarrow%20s%3D455165.2777%5C%20m)
The bird will fly 455165.278 m
The tension in the rope B is determined as 10.9 N.
<h3>
Vertical angle of cable B</h3>
tanθ = (6 - 4)/(5 - 0)
tan θ = (2)/(5)
tan θ = 0.4
θ = arc tan(0.4) = 21.8 ⁰
<h3>Angle between B and C</h3>
θ = 21.8 ⁰ + 21.8 ⁰ = 43.6⁰
Apply cosine rule to determine the tension in rope B;
A² = B² + C² - 2BC(cos A)
B = C
A² = B² + B² - (2B²)(cos A)
A² = 2B² - 2B²(cos 43.6)
A² = 0.55B²
B² = A²/0.55
B² = 65.3/0.55
B² = 118.73
B = √(118.73)
B = 10.9 N
Thus, the tension in the rope B is determined as 10.9 N.
