The airplane is traveling in a straight line with a speed of $300 \mathrm{~km} / \mathrm{h}$, when the engines $A$ and $B$ produce a thrust of $T_{A}=40 \mathrm{kN}$ and $T_{B}=20 \mathrm{kN}$, respectively. Determine the angular velocity of the airplane in $t=5 \mathrm{~s}$. The plane has a mass of $200 \mathrm{Mg}$, its center of mass is located at $G$, and its radius of gyration about $G$ is $k_{G}=15 \mathrm{~m}$.

Key Concepts

Moment of Inertia

This is a measure of an object's resistance to angular acceleration about a given axis. In rotational dynamics, it plays a similar role to mass in linear motion. The moment of inertia can be calculated using the formula I = m * k^2, where m is the mass and k is the radius of gyration, summarizing how the mass is distributed relative to the axis of rotation.

Net Torque

Net torque is the sum of all the moments (or turning effects) produced by forces acting on a body, calculated as the product of force and its lever arm distance from the axis of rotation. It is essential in determining the rotational acceleration of an object, as it provides the overall effect of forces that are not aligned with the center of mass.

Angular Acceleration

Angular acceleration is the rate of change of angular velocity over time. It is determined by the net torque acting on an object divided by its moment of inertia, according to the relation ? = ? / I. This key concept links the applied forces (through net torque) to the rotational motion of the body.

Rotational Kinematics

Rotational kinematics involves the equations that describe the motion of objects under angular acceleration, analogous to the kinematics of linear motion. Given a constant angular acceleration, one can determine the change in angular velocity over time using equations like ? = ?? + ?t, where ?? is the initial angular velocity and t is time.
