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:

Step1: Draw a circle

Draw a circle to represent the path of the object's motion.

Step2: Mark two positions

Mark two points on the circle to represent two positions of the object.

Step3: Draw velocity vectors

At each marked - point, draw an arrow tangent to the circle. This arrow represents the velocity vector of the object, since the velocity of an object moving in a circle is always tangent to the circle at any given point.

Step4: Draw centripetal - acceleration vectors

At each marked - point, draw an arrow pointing towards the center of the circle. This arrow represents the centripetal acceleration vector, as centripetal acceleration always points towards the center of the circular path for an object in circular motion.

Answer:

A hand - drawn top - view diagram 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.
