Consider a bird that flies at an average speed of 10.7 m/sm/s and releases energy from its body fat reserves at an average rate of 3.70 WW (this rate represents the power consumption of the bird). Assume that the bird consumes 4.00g4.00g of fat to fly over a distance dbdbd_b without stopping for feeding. How far will the bird fly before feeding again

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

Time required to burn the fat

Distance traveled by the bird

The bird will fly 455165.278 m

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
