When plane is flying along the wind then we can say
Now when its going against the wind the speed is given by
Now by the above two equations we will have
Answer:
A. Its translational kinetic energy is larger than its rotational kinetic energy.
Explanation:
Given that
Radius = R
Mass = M
We know that mass moment of inertia for the solid sphere
Lets take angular speed =ω
Linear speed =V
Condition for pure rolling , V= ω R
Rotation energy ,RE
RE= 0.2 MV²
The transnational kinetic energy TE
TE= 0.5 MV²
From above we can say that transnational energy is more than rotational energy.
Therefore the answer is A.
