Answer:
Why do insects fly so high?
Because the angle of attack is so high, a lot of momentum is transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag. The important feature, however, is the lift.
Why an Aeroplane flying has kinetic
A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energ

Explanation:
The centripetal acceleration of a planet is equal to the acceleration due to gravity.
ac = g
Centripetal acceleration is:
ac = v² / r
where v is velocity and r is radius of travel.
Acceleration due to gravity is:
g = GM / r²
where G is gravitational constant, M is the mass of the sun, and r is the radius of travel.
Therefore:
v² / r = GM / r²
v² = GM / r
v = √(GM / r)
Distance is speed times time, so:
d = v t
2πr = √(GM / r) t
t = 2πr √(r / (GM))
t = 2π √(r³) / √(GM)
We know that when r = 1 AU, t = 1 year.
1 = 2π √(1³) / √(GM)
1 = 2π / √(GM)
2π = √(GM)
Substituting:
t = 2π √(r³) / (2π)
t = √(r³)
When r = 3AU:
t = √(3³)
t = 5.2
Planet B takes approximately 5 years to orbit the sun.
