Answer:
a) 
b) 
Explanation:
From the question we are told that:
Velocity of eagle 
Frequency of eagle 
Velocity of Black bird 
Speed of sound 
a)
Generally the equation for Frequency is mathematically given by



b)
Generally the equation for Frequency is mathematically given by



Added because force increase as it experiences drag.
Answer:
The astronaut's acceleration is 155.1 times the vehicle's acceleration
Explanation:
These effects due to Newton's third law of action and reaction. Since the forces are equal but in the opposite direction and each acting on a different body. We distance that the Force is F let's calculate the acceleration of the vehicle and the astronaut
Astronaut
F =
a₁
Vehicle
F =
a₁
F = 555.1
a₂
Let's match the equation
a₁ = 155.1
a₂
a₁ = 155.1 a₂
a₁ / a₂ = 155.1
The astronaut's acceleration is 155.1 times the vehicle's acceleration
We see that even when the acceleration of the vehicle is small, there is a very high multiplicative factor.
One method to improve this situation is that the vehicles fear some small retro-rocket vehicles to reduce their acceleration. This would have a very favorable impact on the astronaut's mission.
Another method would be for the astronaut himself to have the retro-rocket and control his acceleration.
The Mechanical Energy is given by the sum of the all energies of the system.
