Final answer:
In a uniform circular motion, the velocity is tangent to the circular path, while the acceleration and net force point towards the center, which are represented by the centripetal acceleration and force respectively.
Step-by-step explanation:
To understand which set of vectors describes the velocity, acceleration, and net force acting on a cylinder in circular motion, we need to recall the concepts of uniform circular motion. When an object moves in a circular path at a constant speed, the velocity vector is always tangent to the path, indicating the direction of motion. The acceleration vector, known as the centripetal acceleration (ac), points towards the center of the circle, which is also the direction of the net force that causes this acceleration, known as the centripetal force. This force is necessary to keep the object moving in a circular path. The magnitude of this acceleration is given by the formula ac = v2/r, where v is the linear speed and r is the radius of the circle.
Therefore, the best set of vectors that describes these quantities for a cylinder moving in a circular path at the indicated point would be with the velocity tangent to the path, and both the net force and acceleration pointing towards the center of the path.
