Which of the following is true about a rigid body in dynamic equilibrium? The body can have translational motion, but it cannot have rotational motion. The body can have translational motion and rotational motion, as long as its translational and angular accelerations are equal to zero. The body cannot have translational motion, but it can have rotational motion. The body cannot have translational or rotational motion of any kind.

Answer:

The correct answer is "The rigid body can have rotational and transnational motion, as long as it's transnational and angular accelerations are equal to zero."

Explanation:

A rigid body by definition does not deform when forces act on it. In case of static equilibrium a rigid body cannot have any sort of motion while in case of dynamic equilibrium it can move but with constant velocities only thus having no acceleration weather transnational or angular.
