Question

create a top view of an object moving in a circle at constant speed, such as a ball on a string. show at least two positions of the object. at each position, draw an arrow for the objects velocity and another arrow for the centripetal acceleration of the object.

Explanation:

1. Draw a circle to represent the path of the object. Mark two points on the circle to show different positions of the object.
2. The velocity vector at any point on the circular path is tangent to the circle at that point, indicating the direction of the object's instantaneous motion.
3. The centripetal - acceleration vector points towards the center of the circle at each position, as centripetal acceleration is always directed towards the center to keep the object moving in a circular path.

Answer:

A top - view drawing with a circle, two marked positions on the circle, velocity vectors tangent to the circle at the marked positions, and centripetal - acceleration vectors pointing towards the center of the circle at the marked positions.
