The question is asking for the acceleration of A relative to B. What's the acceleration at A and at B independently?nysnacc said:

should be tangential because constant radius??Student100 said:

Relative motion in a circle refers to the motion of an object or point in a circular path with respect to another object or reference point. It is the perception of movement from the viewpoint of a moving observer.
Absolute motion is the actual movement of an object in space, while relative motion is the perceived movement of an object from the perspective of an observer. Absolute motion is measured with respect to a fixed point, while relative motion is measured with respect to another moving point.
The relative motion in a circle can be calculated using the formula v = ωr, where v is the tangential velocity, ω is the angular velocity, and r is the radius of the circle. This formula relates the linear and angular velocities in a circular motion.
Centripetal acceleration is the acceleration that an object experiences when moving in a circular path. In relative motion, it is the acceleration experienced by the object with respect to the moving observer. It is always directed towards the center of the circle.
Some examples of relative motion in a circle include the motion of a car around a roundabout, the rotation of the Earth around the Sun, and the motion of a satellite orbiting around the Earth. These motions can be observed from a stationary reference point, such as the ground, and appear to be moving in a circular path.
